Problem

My problem is related to labeling sections for future labeled section transclusion. Let's say I have the following page:

<section begin=foo />

Some text.

<section end=foo />

Instead of having the raw section tags, though, I want to have two templates:

Template:BeginFoo

<section begin=foo />

Template:EndFoo

<section end=foo />

such that I can do the following:

{{BeginFoo}}

Some text.

{{EndFoo}}

The problem is, this doesn't seem to work! Looking at the DPL code, I'm guessing this is because the section tag is rendered to an empty string, so when the BeginFoo template is transcluded, the section tag is rendered and not actually present in the calling page.

Workaround

The only workaround I can think of is to call

{{subst:BeginFoo}}

Some text.

{{subst:EndFoo}}

but that is less than desirable.

Indeed DPL relies on the fact that the section tag is physically present within the raw wiki text. Maybe DPL could learn to understand someting like {{begin section|Foo}} but I can´t see an advantage in this.

The intended use

Here is the advantage (or at least why I am interested):

I am trying to use DPL to be the framework behind a nice RSS feed infrastructure, much like what Dmb was talking about. For example, let's say I have an article called Blog Entry; in that article I could do something like:

Some text...

{{BeginFeed
|date=2008/03/25
|author=[[User:Gero|Gero]]}}

This text will appear as a new entry in the RSS feed.

{{EndFeed}}

where the BeginFeed and EndFeed templates would add section tags as described above.

Then, I could have a separate article, called something like BlogFeed to aggregate all of the feed items using DPL:

<dpl> 
uses=Template:BeginFeed
include=feedcontent,{BeginFeed}:date,{BeginFeed}:author
ordermethod=firstedit
order=descending
format=,[[%PAGE%|%TITLE%]],,
</dpl>

(this of course is not a functioning example; I still have to add some code to re-order the entries based upon the user-defined date given to the BeginFeed template)
