You're right - I haven't found any pointer.
So I added one (small).
Basically I have seen <classpath>s & Co inside targets before tasks or in an
"init-target" (required in early Ant versions - now you could place that
directly under 'project' as implicit target).

Betreff: targets and data types
I have some targets that define data type instances, such as file lists.
Nothing surprising about that, except that when I look at the Ant User Manual,
I find nothing that says that a target can contain a data type. I didn’t see
any examples of targets containing data types, either.
Looking at the code for Target, it is clear that a Target contains tasks and
data types.
So, I’m wondering why I can’t find any mention of targets containing data types
in the user manual. Did I miss it, or is it really not there?
The background for this question is that I am thinking of replacing a macro
with a custom task, where the macro expands to a sequential execution of some
datatypes. That sounds impossible, but yet it works. Should I not be doing
this? I feel like I am missing something important.
Here’s the example:
<macrodef name="classpath">
<element name="classpath-elements" optional="true"/>
<element name="jars-elements" optional="true"/>
<element name="include-elements" optional="true"/>
<sequential>
<path id="lib.jars.elements">
<jars-elements/>
</path>
<path id="lib.include.elements">
<include-elements/>
</path>
<path id="lib.path.elements">
<classpath-elements/>
</path>
</sequential>
</macrodef>
