Funnily enough (as it always is!) - we've been having problems with a
new version of xerces on the WBL project that I supervise. It just keeps
coming back with things that arent wrong - for example, it claims an
entity isnt defined when it quite plainly is (and the other entities in
the same file are OK, and also theres an attempt to load local.ent by
uising a relative path not an absolute**. the relative path is something
like
"../../../../../../../../ents/lusid.ent"
the parser claims that the file
/lusid/uk/ac/liv/pages/test/../../ents/lusid.ent
doesnt exist - well I know it doesnt thats why the path is pointing else
where - it just seems to ignore the first part of the path. Got no idea
at all what is going on - it works fine with abs paths - can the parser
be full of bugs?
What is the line which is supposed to be causing problems in cqdefs?

** that reminds me the liverpool page tree that I sent had absolute
paths to the ents files so they wont be found on your server - sorry!

|Solaris 8
