PaceVersionAsText

[Antone Roundy <antone@xxxxxxxxxxxxxx>]

Whether the version is a number, something resembling a number (eg. a 
dotted triple (sorry, not RDF) like 0.5.2) or text, it would be useful 
to have some structure in the version string so that a number or 
something resembling one could be extracted from it easily.  I'd 
imagine there will be things in, for example, version < 1.5 or 1.2 < 
version < 1.8.3 or version >= 2.0, etc.  Being able to quickly extract 
that number and do numeric comparisons to know how to handle certain 
things would be good.

Having some sort of structure would require a change to the proposal, 
since it proposes saying "The format of this attribute is unstructured 
text."

Maybe we could use something like <feed version="0.5.1; 
draft-ietf-atom-format-04.txt; do not implement this"> where everything 
before the first semicolon is number-like, and everything after it is 
unstructured text.
