PCDATA-type:
<Message>
<Query>Name</Query>
</Message>
with the response:
<Message>
<Answer>
<Name>Foo</Name>
</Answer>
</Message>
Tag-type:
<Message>
<Query>
<Name/>
</Query>
</Message>
with the same response as above.
As I see it, the tag type has the advantage that it is the same tag
(eg. <Name>) in the query as in the answer. You can limit the queries to
the same tags allowed for the answers in a DTD. On the other hand it takes
a bit more effort to find what you query for.
