xml-dev - Bug in XML::Parser declaration handling

[Clark Cooper <coopercc@netheaven.com>]

Ken Beesley <ken.beesley@xrce.xerox.com>, discovered that, in Version 2.25
of XML::Parser, the Attlist and Element handlers aren't being called
for declarations in the external DTD when there is no internal subset.

So, for example, given these files:

junk.dtd:
  <!ATTLIST foo bar CDATA 'junk'>

junk.xml>
  <!DOCTYPE foo SYSTEM 'junk.dtd'>
  <foo/>

junk2.xml:
  <!DOCTYPE foo SYSTEM 'junk.dtd' []>
  <foo/>

This script:
################
use XML::Parser;
$p = new XML::Parser(ParseParamEnt => 1,
                     Handlers => {Start => sub {shift; print "Start: @_\n"},
                                  Attlist => sub {shift; print "Att: @_\n"}});
$p->parsefile('junk.xml');
print "--Next File--\n";
$p->parsefile('junk2.xml');
################

produces this output:
================
Start: foo bar junk
--Next File--
Att: foo bar CDATA 'junk'
Start: foo bar junk
================

So, until I get this bug fixed, a workaround is to put in an empty internal
subset as necessary.
