Thanks for pointing that one out. And that would work fine for focus on one node, except that the result of a search will be perhaps many distinct nodes, some of which will share parentage, and some of which will have distinct parentage. That darn "0 or more but usually 1" parent thing gets in the way.

And yes, I agree with perrin on this one, but the client has chosen to mix links of both "is-like-a" and "contains-a" in the same syntax net. Ugh.
