Re: [xml] Parsing <?xml decl with xmlReader

Excellent idea!

That should be as simple as adding the following line near the start of
xmlParseXMLDecl, eg. on line 8902 of parser.c:

    ctxt->input->standalone = -2;

This will be overwritten later if an actual standalone pseudo-attribute is
found in the XML declaration.

Then it is possible to check if the document has an XML declaration simply
by checking that doc->standalone != -1:

    standalone = 1              standalone="yes"
    standalone = 0              standalone="no"
    standalone = -1             no XML declaration
    standalone = -2             XML declaration but no standalone attr

Does this all sound reasonable? If so, should I submit the above line as a
patch?

Best regards,

Michael
