Privde some sort of method of specifying named transformation. Something like:
<transform
element
=
"fubar"
>
<source
attribute
=
"pattern"
>
regex pattern for matching
</source>
<target
value
=
"true"
>
regex pattern for replacement
</target>
</transform>
which would make the following valid:
<fubar
pattern
=
"^:Ws.+}"
>
replacement
</fubar>
