Processing the xml declaration line
Is there some way to get the XML declaration to act like a standard
processing instruction so I can handle it with the processInstruction
callback? I am talking about the line:
<?xml version="1.0" encoding="UTF-8"?>
If I cannot handle it as a processing instruction, can I ask the parser
for it any other way? I cannot seem to find it in the doc. Thanks.

SAX2 Extensions 1.1 exposes the encoding and version of the current entity
through the Locator2 interface. In the version of SAX being discussed on
the xml-dev list, there's a new property called document-xml-version which
returns the version of the document entity. Hopefully both Extensions 1.1
and this new minor version of SAX will be final soon. I'm currently
working on support for the extensions and new version of SAX (I'm
guessing it will be 2.0.2). The plan is to include this in the next
version of Xerces.

The W3C's been very explicit about the XML Declaration *NOT* being a
Processing Instruction, even if it looks like one.
DOM Level 3 Core (just announced as a Recommendation) adds calls to
retrieve information from the XML Declaration. I'm not sure how much of it
is available in SAX.

Hi Ben,
The Document and Entity interfaces from DOM Level 3 Core[1] (which is now a
W3C Recommendation) contain attributes named xmlEncoding[2][3] and
xmlVersion[4][5] that represent the version and encoding attributes of an
XMLDecl and TextDecl. This might help you achieve what you want.
