... looks like one can always feel safer, if limiting
himself to use only brutal XML subset, such as
PXML (which is : attributes, elements, mixed content.
No namespaces / comments / entities e t.c.)

I also agree that skipping WF parsing is 'not right'
( using XML subset or not ).
For myself, when I need some XML processing, I now
use XML Chunks ( http://www.pault.com ), it is fast and clean.
I take the output from XSLT ( XQuery ) , I read it into Chunk,
I can ( and I do ) tune Chunks with perl's regular expressions - it is
like having regular expressions in XSLT. I like it.
"Avoid XML parsing, replace it with some binary format"
sounds 'not right'.
