Hm, I think we need both ;-)
I thought a lot about having access inside Java (Action, Transformer ..)
JXPath or the flow access to the Sitemap Variables. I think this really
make sense. Global sitemap variables are now accessible using the
SitemapVariableHolder Component. Why not writing a
(RequestLifecyle)Component which also has access to the "dynamic" Sitemap
variables ? Other Idea is, storing an read only JXPathContext inside the
Sitemap which holds the "global variables" and the "dynamic" too. Inside
the java code we can create a JXPathContext which has this Context as an
parent...vola... now we have have access to everything we need using this
context.

Only random thinking without thinking alot about ;-)
What do other think?
