Alexander Barkov f5a850109a Bug#38227 EXTRACTVALUE doesn't work with DTD declarations 
Problem:
 XML syntax parser allowed to use quoted strings as attribute names,
 and tried to put them into parser state stack instead of identifiers.
 After that parser failed, if quoted string contained some slash characters.
Fix:
 - Disallowing quoted strings in regular tags.
 - Allowing quoted string in DOCTYPE declararion, but
 don't push it into parse state stack (just skip it).
