I agree that actions-sets do have some shortcomings. But I would
argue that they should be abandoned instead of tinkered with. Instead,
a macro like system would be more useful: something like a resource
but that does _return_ (OK, you *could* use XML entities for that).
It would give you any flexibility you want and wouldn't be limited to
actions-sets. For those, you could use any selector that uses whatever
scheme you would like to use.
I am quite sure that having that ability would solve many if not all
problems that you are facing.

IMHO such a multi-action does not need to be supported by the
sitemap. We have the ability to pass arbitrary parameters to an
action. An action is able to dispatch arbitrary methods. The problem
lies in the restricted flexibility of action-sets.
Thus I propose to have
<map:pipeline-fragments>
<map:pipeline-fragment name="action-set-foo">
<!-- anything that is allowed to be in a pipeline -->
</map:pipeline-fragment>
<!-- more fragments -->
</map:pipeline-fragments>
with
<map:match ....>
<!-- ... -->
<map:use-fragment name="action-set-foo"/>
<!-- ... -->
</map:match>
and (in sitemap.xsl):
<xsl:apply-template
select="/map:sitemap/map:pipeline-fragments/map:pipeline-fragment[name="@name"]/>
Don't know sitemap.xsl good enough by heart whether this would suffice.
There's one shortcoming, though. Today, it is possible for action-sets
to have nested elements whose execution is conditional. It appears
difficult to have this with my suggestion. I'm not sure whether people
use that feature, though.
Chris.
