[xml] XHTML modularisation (on XML-DEV)

["Peter Jacobi" <pj walter-graphtek com>]

Hi Daniel, All,

Did you notice the "XHTML modularisation causes strange error with 
MSXML" thread on XML-DEV, started by 
Benoit MAISONNY eurocontrol int?

He did some tests with different parsers of a complicated set of DTDs 
using XHTML modularisation. He later included libxml2 in his tests
which (nearly) works OK, so only MSXML to blame.

I got one remark regarding the use of relative path in SYSTEM:

I don't know what's the correct behaviour.

The later messages in the thread were more standardese than I can 
understand with reasonable efforts, it seems about good, bad and ugly 
definitions of the standard entitities lt and amp. The libxml2 related part 
was about less than helpfull error messages for obscure cases.

Peter
