/**
* Package {@code javax.print.attribute.standard} contains classes for specific
* printing attributes. The parent package, <a href="../package-summary.html">
* javax.print.attribute</a>, provides classes and interfaces that describe the
* types of Java Print Service attributes and how they can be collected into
* attribute sets.
* <p>
* An attribute represents a printing feature that a print service can provide.
* For each attribute, a print service either does or does not support the
* attribute. For each possible value of a supported attribute, a print service
* either does or does not support the value.
* <p>
* The API requires every print service to support certain attributes; other
* attributes are optional and the service can choose whether or not to support
* them. Each attribute has a set of values that it accepts. The API requires
* every print service to support certain values for certain attributes; other
* attribute values are optional and the service can choose whether or not to
* support them. These support requirements are recorded in the documentation
* for each attribute class.
* <p>
* Package {@code javax.print.attribute.standard} contains standard printing
* attributes and standard printing attribute values that are widely used in the
* printing domain. A print service vendor can provide new vendor-specific
* printing attributes in addition to the standard ones. A vendor can also
* provide vendor-specific extensions (subclasses) of the standard printing
* attributes -- for example, to provide additional vendor-specific values for
* an existing standard attribute. Of course, if a vendor wants clients to be
* able to use any added or extended attributes, the vendor must publish the new
* attribute classes.
* <p>
* Many of the standard attribute classes extend one of the abstract syntax
* classes of the {@code javax.print.attribute} package. These abstract syntax
* classes each represent a different type. The <a href="../EnumSyntax.html">
* EnumSyntax</a> class, for example, represents a type-safe enumeration. The
* abstract syntax class provides a wrapper for the attribute value.
* <p>
* If an attribute class extends {@code EnumSyntax}, and the value of the
* attribute is an IPP-compatible value, the attribute's {@code toString} method
* returns the IPP string representation of the attribute value, such as
* "processing-stopped" for the <a href="JobState.html">JobState</a> attribute.
* However, because the {@code EnumSyntax} class is extensible, vendors can
* define their own attribute values. If an attribute uses the
* {@code EnumSyntax} class and is set to one of these vendor-defined values
* then the {@code toString} method will not return the IPP string
* representation of the value.
* <p>
* A printing client application will typically not need to use all the printing
* attribute classes in package javax.print.attribute.standard, just the ones
* that pertain to the application.
* <p>
* The attribute classes in package {@code javax.print.attribute.standard} are
* based on the Internet Printing Protocol (IPP) attributes as defined in the
* Internet RFC document, <i>RFC 2911 Internet Printing Protocol/1.1: Model and
* Semantics</i> dated September 2000. See
* <a href="http://www.ietf.org/rfc/rfc2911.txt">RFC 2911</a> for more
* information. The descriptive text for each attribute class was taken largely
* from the above documents. The above authors' contribution to the API is
* gratefully acknowledged.
*
* <h3>Attribute Organization</h3>
* There are five kinds of printing attributes: doc attributes, print request
* attributes, print job attributes, print service attributes, and
* supported-values attributes.
*
* <h4>Doc Attributes</h4>
* Doc attributes specify the characteristics of an individual doc and the print
* job settings to be applied to an individual doc. A doc attribute class
* implements interface <a href="../DocAttribute.html">DocAttribute</a>. A doc
* attribute can appear in a <a href="../DocAttributeSet.html">
* DocAttributeSet</a>.
*
* <h4>Print Request Attributes</h4>
* Print request attributes specify the settings to be applied to a whole print
* job and to all the docs in the print job. A print request attribute class
* implements interface <a href="../PrintRequestAttribute.html">
* PrintRequestAttribute</a>. A print request attribute can appear in a
* <a href="../PrintRequestAttributeSet.html">PrintRequestAttributeSet</a>.
* <p>
* Some attributes are doc attributes but not print request attributes and may
* only be specified at the doc level. Some attributes are print request
* attributes but not doc attributes and may only be specified at the Print
* Request level. Some attributes are both doc attributes and print request
* attributes and may be specified either at the doc level or at the Print
* Request level.
* <p>
* When specified at the doc level, an attribute applies just to that one doc.
* When specified at the Print Request level, an attribute applies to the whole
* job, including all the docs in the job. However, an attribute specified at
* the doc level overrides an attribute in the same category specified at the
* Print Request level.
*
* <h4>Print Job Attributes</h4>
* Print job attributes report the status of a Print Job. A print job attribute
* class implements interface <a href="../PrintJobAttribute.html">
* PrintJobAttribute</a>. A print job attribute can appear in a
* <a href="../PrintJobAttributeSet.html">PrintJobAttributeSet</a>.
* <p>
* Some attributes are both print request attributes and print job attributes; a
* client may include such attributes in a Print Request to specify
* characteristics for the ensuing Print Job, and those attributes then also
* appear in the Print Job's attribute set. Some attributes are print job
* attributes but not print request attributes; the print service itself adds
* these attributes to the Print Job's attribute set.
*
* <h4>Print Service Attributes</h4>
* Print service attributes report the status of a print service. A print
* service attribute class implements interface
* <a href="../PrintServiceAttribute.html">PrintServiceAttribute</a>. A print
* service attribute can appear in a <a href="../PrintServiceAttributeSet.html">
* PrintServiceAttributeSet</a>.
*
* <h4>Supported-Values Attributes</h4>
* A supported-value attribute indicates the legal values for another attribute
* that a print service supports. A supported-values attribute class implements
* interface <a href="../SupportedValuesAttribute.html">
* SupportedValuesAttribute</a>. However, supported-values attributes never
* appear in attribute sets, so there is no restricted
* <a href="../AttributeSet.html">AttributeSet</a> subinterface for them.
*
* <h4>Attribute Table</h4>
* The table below lists all the printing attributes. The table shows the
* tagging interfaces each attribute class implements in addition to interface
* <a href="../Attribute.html"> Attribute</a>, thus indicating how each
* attribute is used in the API. For each doc attribute and print request
* attribute, the column marked "SupportedValuesAttribute" lists the
* supported-values attribute class, if any, with which a print service
* indicates the supported values for that attribute category.
* <table border=1 cellpadding=2 cellspacing=1 summary="Lists all printing
* attributes as described in above text">
