getAdditionalTemplateResourceNames()
With this method the interceptor can define additional template files which should be added to the template
engine that custom fragments are available during processing

getPriority()
In case that an application has different interceptors intercepting on the same replace call, the first
interceptor will win.

ReplaceTagProcessor
before executing the ordinary replace logic as
implemented by the StandardReplaceTagProcessor
. With this method the interceptor can decide to overwrite
the attribute value of the replace tag to call another target fragment instead. Probably the interceptor also has
to add additional variables to the context if the other target fragment has parameters which does not exist in
the given context If the interceptor wants to intercept, it has to modify the attributeValue and call the
doProcess method of the given tagProcessor. It has to return true to indicate that processing was done within
this interception to avoid another processing by the ReplaceTagProcessor
