I also thought of "id", but I'd like to avoid this no-duplicate
constraint, hence "name" : a sitemap is often consituted of similar
pipeline patterns, and the same name will IMO often be associated with
statements having the same role in different branches of the sitemap.
Example :
<map:pipeline>
<map:match pattern="foo-*" name="topmatcher">
<deep-nesting...>
<map:generate src="foobase-{#topmatcher:1}"/>
</deep-nesting...>
</map:match>
<map:match pattern="bar-*" name="topmatcher">
<deep-nesting...>
<map:generate type="bar" src="{#topmatcher:1}"/>
</deep-nesting...>
</map:match>
</map:pipeline>
An important difference between a sitemap and an Ant file is that
pipeline construction follows a path in the sitemap hierarchy, and thus
a statement cannot use variables defined by a statement that isn't one
of its ancestors. This isn't true in Ant files where targets can be
referenced from anywhere in the file.
I also discussed about name overloading on a single path at
http://marc.theaimsgroup.com/?l=xml-cocoon-dev&m=103432718409833&w=2
I guess you may not like this overloading. In that case, what about
requiring uniqueness of names _on a path_, meaning the same name can be
used in different branches of the sitemap tree ?
