Dmitri,
org.apache.tools.ant.ProjectHelper has some methods that are used for
property expansion. I don't believe you have a handle to the Project
instance in XDocletTagSupport, but if you do then call replaceProperties.
If not, then you could use parsePropertyString to do the work for you (if
you go this route, you can borrow the code in replaceProperties).
The problem that exists now is that XDocletTagSupport.getParameterValue
appears to be a bug in dereferenceProperty that only returns the property
value and not the surrounding text also - although it was tough to navigate
through getParameterValue's logic enough to truly diagnose it. If you
substitute the use of ProjectHelper.parsePropertyString at least, and
perhaps even replaceProperties into dereferenceProperty you'll likely have
it fixed.
