I refer you to my previous response when you asked this question:

http://lists.zope.org/pipermail/zope-cmf/2002-September/015029.html

The problem is known, and is the result of, if I understand correctly, a 
piece of legacy code in CMF which gets in the way of the proper processing 
of structured text. I've just added a followup to the collector item with a 
patch which fixes the bug *for me*. It may have side effects which I 
haven't noticed. Also I haven't tested it against even the released version 
of CMF 1.3, so ymmv.

If you don't grok "patch", find the place in CMFCore/utils.py which looks 
like this:

                 , expr2 = re.compile( _STXDWI._DQUOTEDTEXT
                                     + r'(\,\s+)'
                                     + _URL_AND_PUNC
                                     + _STXDWI._SPACES
                                     ).search

and replace it with this:

                 , expr2 = re.compile( r"[\,\.\?\!\;]+" ).match

Can't help with this I'm afraid. I've noticed some odd behaviour, and it 
likely has a similar cause to the above. I use stx quite a lot, so I may 
get round to looking at this in a couple of months.

Yeah, it's ugly, though, isn't it!

The STX functionality is wrapped by a class (CMFDocumentClass) in 
CMFCore/utils.py - for what reason I don't personally know. I'd imagine 
that "level" just controls which HTML header level the STX top level 
corresponds to (but that's a guess). I'm pretty sure it's not causing what 
you're seeing here.
