I've been watching the extensive discussions about input modules for

transformer that allows access to data from input modules? Something
that allows values to be accessed and placed in the SAX stream?

There is a LinkRewriterTransformer which does this for certain
attributes:

(and Chris just committed.. thanks)

It would be simple to modify this to replace ${module:key} tokens in the
SAX characters() method,

If you do this - don't forget to buffer all characters() before doing replacements.

rather than attribute values.

How does this compare to ro correlate with the session transformer that
originated with the portal component donation? Are they / should they
be the same?

Didn't know about it, hidden away in a block.. it looks quite powerful.
Anything based on InputModules can only do string->string conversion, so
I don't think there's too much overlap.

I have found the session transformer invaluable in many
cases, but it seems to me that extending it to use input modules would
REALLY be useful.... thoughts?
