I'll need to see some examples. Anyways, the current code is already
parsing the mixed content

No no, whatever expression you want. The only issue is that spaces are
being eaten. Imho to make it a good mini template languages we'd have
to preserve spaces instead.
As an alternative, I can roll in a function that behaves like a real
template language, freemarker. I have an experiment in a geoserver
community module that looks more or less like this:
<ogc:Function name="freemarker">
<ogc:Literal><![CDATA[<html><body>
This is bridge <b>${FID.value}</b> whose name is <i>${NAME.value}</i>
</body></html>]]></ogc:Literal>
</ogc:Function>
(FID and NAME are attribute names of the current feature)
Yet, that would require quite a bit more work since that function
requires the support geoserver is providing to wrap gt2 features
into a freemarker model.
Cheers
Andrea
