RequestModule

[Ralph Goers]

I'm trying to test the change to JXPathHelper and have run into problems 
on the RequestModule sample. It fails in JXPath trying to process the 
attributeNames. The problem occurs because the attributeNames member of 
ReqeustWrapper is represented by an IndexedPropertyDescriptor instead of 
a PropertyDescriptor. When JXPath calls ValueUtils.getValue() it fails 
because the getReadMethod call returns null. This is because it is 
returned in getIndexedReadMethod instead.

This does not happen in BRANCH_2_1_X where attributeNames is represented 
by a PropertyDescriptor.

I believe this is happening because in trunk getAttributeNames is now 
overloaded where it wasn't in 2.1.x. The only way I can think of to fix 
this is to leave getAttributeNames() as is (returning the attribute 
names that are of global scope) and replace getAttributeNames(int scope) 
with getLocalAttributeNames() and have it only return the local 
attribute names.

Any other ideas?
