An ELNode should be able to iterate over all childnodes.

This is convenience. Currently, you can do on a ELNode x:

x.node['somename'] --> ElNode
x.nodes['somename'] --> List of nodes

but not :

x.nodes

x.nodes should return a List.

Hence, AstractELNode and ContenELNode should have a seperate ELPseudoMap where ELPseudoMap must also be a list. Then, jsp expression language can do x.nodes because it will get an iterator from the list
