[pmwiki-users] Is it possible to create and use page-scoped variables?

[OBUTEX / Hladůvka]

Just an idea as I'm not PHP programmer.

What about to deffer properties to "static" performed before
and "dynamic" performed after a cond.markup
then could be
(:property type=static testing true:)  and
(:property type=dynamic message "You don't have permission to edit":)

or another aproach:
the usage of  a property in the cond. markup assumes the property's 
value is allready set.
Usage of the property inside the conditional body block means the 
property is to be
evaluated after evaluating the condition.
