In testing, inside the IF-THEN Construct, or in the Conditions block of
a Rule, could we get the ability to look at other objects with Source
Attribute, like we can with a token-src-attr?

I.e. In Arguement Builder we can say Source Attribute of an object and
get three options. Current object, Association value, or DN.

Could we get those options in the condition block?

I find I have to set a local variable to the Source Attr first, then I
can test if local variable = something...

Instead of just testing if source attr from the DN specified by
SOMETHING is equal...
