Hum... OGC filter against features is xpath based. Soo... when I say a = 10 against a simple feature the corresponding xpath filter would be: feature[a = 10] whilst doing what you say against a complex one would result in: feature[a/b/c = 10] where, as you say, some between a, b or c is multivalued (so we're actually looking at a list if not a tree). Is this even valid? What would it mean? Afaik you can do something like: feature[a/b/c[1] = 10] that is, select the specific subelement to test (assuming c is the multivalued bit). But what would be the meaning of the former writing? all a/b/c subelements must be equal to 10? Just one? Afaik the xpath engine would return a list of elements and the comparison would fail.
