XOM API for Processing XML with Java

[Wolfgang Hoschek <whoschek AT lbl.gov>]

xom-1.1-CVS with Crimson JDK 1.4 (but not xerces-2.6.2) has a bug when 
using doc.setInternalDTDSubset(doc. getInternalDTDSubset()) with the 
document below. Interestingly, the document parses fine when using 
crimson with new Builder().build(...). I'm wondering if anything could 
be done about it?

<?xml version="1.0"?>
<!DOCTYPE doc [
  <!ELEMENT doc (#PCDATA|a|b|c)*>
  <!ATTLIST doc id ID #REQUIRED>
  <!ELEMENT a (#PCDATA|a|b|c)*>
  <!ATTLIST a id ID #REQUIRED>
  <!ELEMENT b (#PCDATA|a|b|c)*>
  <!ATTLIST b id ID #REQUIRED>
  <!ELEMENT c (#PCDATA|a|b|c)*>
  <!ATTLIST c id ID #REQUIRED >
]>
<doc id="id0"></doc>
