Yeah.  Looking at your link it looks like using "!merge" (without the colon) will probably work.  just need to test it.  That goes along with what it says in the wiki except for the fact that the wiki says it "can" be used instead of saying it must.

Maybe there's something useful for you here.

I've only once used the attribute knockout functionality -- what is
your use case? There may be another simple solution.
