Feeler for SML (Simple Markup Language)

Don:
I think it is an interesting idea but not good for the XML
community as a whole. XML is already very fragmented and confusing to the
'newbie'. If you ask 10 people who have heard about XML but are not
ingrained in the XML specification - "What is XML?", I guarantee you will
get at least 8 different answers. By adding another subset and 'ML' into
the mix we will add considerable confusion. Individuals can now scale XML
down for their own purposes. You can do the same scaling with any other
computer technology, JAVA, Perl, etc. Use what you need.
I have reading the threads from the last few days with interest
though. It took me a few moments this morning to realize Rick's message
this morning on XML 2.0(alpha) was a joke. In all fairness it was before
my morning coffee but I did almost have a slight coronary |-).
Just a couple of comments on recent posts on external parsed
entities and Unique ID's:
Eliot - I never knew you thought parsed entities were 'evil'. I knew
you didn't particularly like them but the 'Darth Vader of XML'
|-). I also agree with you that the 'valueref' of HyTime would
be extremely useful - but XLink should do the job.
Like, Ken, I have found external entities to be really useful in creating
reusable components. However, IDs and parsed external entities have a
tendency to be problematic - even in a controlled environment. They will
be even more problematic when we really start creating 'global' documents,
i.e., virtual catalogs.
