When people design markup languages, they can't always predict every
use the information in the XML documents will be put to, plus they
don't necessarily know the strengths/limitations of every method of
processing the document. (It would be straightforward to sum amounts
with units using DOM or SAX, for example.)

Does anyone know of a set of guidelines for designing markup languages
for processing with XSLT? If not, it could be a useful resource to put
together somewhere. Things like:

 - keep numbers and units separate
 - be consistent in case use in attribute/element values
 - use namespaces to embed HTML in XML, not CDATA sections

Any others?
