$webaction-value most likely contains some XSP or Java code at the
time the logicsheet is applied -- which is when the XSP is translated
to Java servlet sourcecode *not* which every request!
So you may not use XSL to check for run time values in a
logicsheet. You need to use Java instead.

Indeed, since it effectively copies the XSP / Java code used to read
the request attribute. It does not, however, copy the _value_ of that
attribute.
