Some value, not the value


Note that there isn't necessarily only one match for a path - often there are many, when it is used on the left side of a rule.

:me.rel:parent

would be "Some x such that I have parent x", and

:me.rel:parent^rel:parent

would mean "Some y such that for some x, I had parent x and y had parent x", or loosely, some sibling of mine.
