Minor syntax clarification here.  I didn't think the splat was a valid part of the 2008 draft.  To use the path expression in the latter case, I would've done this:

	//tmdm:association [ . isa tmdm:topic-name ]

Since this parses (in my understanding) as

Step 1:
	//tmdm:association 	matches		Rule [W] filter-postfix	// anchor

Step 2:
	[ . isa tmdm:topic-name ]	matches		Rule [56] filter-postfix [ boolean-primitive ]

Mostly, I just want to understand that I understand the syntax correctly, as my parser would've choked on your path expression example. ;)

Cheers,

ast
