I would say having an xml syntax but with different meaning for that
syntax would be the worse possible outcome. JSON has a simpler data
model than XML and a different syntax so there is no confusion, but if
microxml has syntax such that it is guaranteed to be well formed xml but
that syntax has a different meaning then that is just building in confusion.

To give a specific example if the comment syntax is allowed

<!-- .... -->

it had better make a comment or (less good but acceptable, be discarded)
what would not be good at all would be if that syntax made an element or
text or some other incompatible thing at the data model level.

If you push for compatibility at the level of syntax only you get things
like html parsing of <foo/> which is accepted syntax but it is a start
tag not an empty tag. I fail to see why that is useful (in general, or
in html)
