I did not know what to do with such attributes as role, whose range of
values is not constrained. Luigi's remark gives me an idea: I should
put a hook in the stylesheet for the user's own formatting
command. Something like \attributeaction[para][role]. The user could
define such an action with something like
\defineXMLattributeaction[para][role].

The attribute action should be invoked within a group in order to
allow the user to change fonts etc. for this element. Therefore
context cannot invoke the attribute action automatically, because it
cannot know where it should do so. For example, some mappings for the
opening tag invoke \egroup; if the attribute action had been invoked
automatically, its scope would be ended immediately.

Groeten, Simon
