This is precisely my attitude toward SML.  Lets just see whats
over the next hill.  If there is a tiger in the hill, I won't
be home for dinner.  If not, I won't be home for dinner. <g>

You brought up an important point which has been rattling in
my brain (it could be a loose bolt) which is: XML fragments
are important.  Your template idea is also important.  What is
missing is the idea of schema fragments which are similar to
XHTML module idea except at a smaller scale, more like molecules
rather than bricks.

Smaller schema fragments can be used to form larger schema
fragments.  A simple schema fragment is a integer data schema
fragment.  Such a schema can be used to to create a domain
specific schema fragment like ZIP code.

I am now leaning very heavily toward focusing SML on XML fragments
so that SML data (the word 'document' is not in the SML draft spec)
starts with the 'content' production rule of the XML spec.  No
prolog, no misc.  SML data have zero or more elements and can be
entirely text.  Interesting thoughts.  I have yet to see clearly
where this line of thinking will lead to but I am having fun.

May your tire pressure remain constant,
