Some EL scope validation ideas triggered by ADF user experience:

1) scoping of expression results.  EL validator, in addition to producing type and LHS/RHS information about an expresson also produces scope information about the model objects referenced.  Useful immediately to generate
warnings on binding attributes that access beans outside request scope.

2) Tag scoping of tag-defined variables.   Useful immediately in finding variables referenced outside their declaring tag (think dataTable var's accidently used outside the dataTable).  Also useful in validating situation below, where a tag defined variable is in tag scope but a variable of that scope type is invalid for an attribute (binding).
