Yes, didn't think about it.

Not sure. I am stuck with this one. But after a little more thinking I came
to conclusion that this one is not true, e.g.:
<generate />
<transform/>
<select type="browser">
<when>
<serialize />
</when>
</select>
And I was wrong thinking that pipelines should be like {aggregate | generate
| call} -> [transform | call]* -> {serialize | call} without intermediate
'select', 'match' or 'act'.

But what about the public identifier and central repository for all DTDs and
Schemas? E.g. XML Spy can get the DTD by HTTP from the server. If
xml.apache.org go Forrest then it'll be the right place for the repository
or at least provide access to sub-project repositories.

Why not the entity catalogue? The main purpose of the Schema for me were
support in sitemap writing, so I'd like it to be in the entity catalogue and
not the sources.
