+     Rules for commits on the gnome-xml module
+     =========================================
+
+If what you are patching is a non-compilation issue either at compile
+time or linking time on one of the main Linux platforms, then feel free
+to patch first and send mail afterward.
+
+Otherwise, send me (Daniel.Veillard@w3.org) a mail and if it's a bug
+issue, register it at bugs.gnome.org. I check both my mail and the
+bug database everyday. if you don't get an answer within 3 days
+(which is highly unprobable) then commit your changes. This simply
+mean that I'm on holliday or on the road.
+
+The reasons I'm asking for an ask before commit policy is that I'm
+using a separate CVS base for unstable developments and if you commit
+a patch I didn't get, I may loose your change by mistake (it happened
+already once) and seriously complicatye my job of merging both bases.
+(The second base is at http://dev.w3.org/ under the XML module).
+
+  thanks in advance for following the rule,
+
+Daniel
+
+P.S.: Raph Levien get an exception for the send before commit rule :-)
