I want to bring one point to the attention of the implementors:
"This new element to set the defaults would not be a data category, but
something all tools using <its:rules> would have to support."

So in addition to the technical issues, we need to think about whether
global implementations of ITS 2.0 will support this, for each data category
they implement. Currently, we have a very clear notion of conformance at


 Processors need to compute the ITS information that pertains to a node in
an XML document. The ITS processing expectations define how the computation
has to be carried out. Correct involves support for <a
="rect">selection mechanism</a>, <a href="#datacategories-defaults-etc"
shape="rect">defaults / inheritance / overriding characteristics</a>, and <ahref
="#selection-precedence" shape="rect">precedence</a>

I would be reluctant to complicate this by saying "some processor MAY
implement parameters, other not".

Any thoughts?
