An xmlParserInput is an input flow for the XML processor.
Each entity parsed is associated an xmlParserInput (except the
few predefined ones). This is the case both for internal entities
- in which case the flow is already completely in memory - or
external entities - in which case we use the buf structure for
progressive reading and I18N conversions to the internal UTF-8 format.</p><p>

The parser context.
NOTE This doesn't completely define the parser state, the (current ?)
design of the parser uses recursive function calls since this allow
and easy mapping from the production rules of the specification
to the actual code. The drawback is that the actual function call
also reflect the parser state. However most of the parsing routines
takes as the only argument the parser context pointer, so migrating
to a state based parser for progressive parsing shouldn't be too hard.</p><p>
