XML Torture Test: Parsers Fail

[Mike Dierken]

The latest internal version of DCXML (from DataChannel) correctly handles
this file and its external entities.
The beta 2 version on our web site may have problems, I don't know one way
or another.

Such a file is now available from
ftp://ftp.metalab.unc.edu/pub/languages/java/javafaq/players.tar.gz
I've fixed the problem with the non-deterministic content model.
I'll be updating that soon with a new file that actually uses all 1000+
entities, as opposed to the current version which defines 1000+ entities
but only uses one. I'll also fix the problems with multiple definitions of
some entities.

After my most recent changes, I now feel reasonably confident that this
file is in fact valid. xmlproc and Java Project X have both been reported
as validating it. IBM's xml4j trips over the relative URLs used in entity
references. I stil don't know what IE5 and the DCXML parsers are tripping
over, but there's definitely something. One parser failed simply because of
the number of entities, and the resulting overflow of Solaris's maximum
number of file descriptors per process.
