Head-marking inconsistent with accentAsHead #473

Closed nkalivoda closed 3 years ago

nkalivoda commented 3 years ago

The notion of head-marking used in the tree-marking option does not fully accord with the notion used by accentAsHead. Consider:

{( a u)} {(LH H*L -)}

This receives 0 violations of accentAsHead, because in Ito & Mester's system "a" is actually the head here.

I don't think we should change the head-marking option, but what would be a good way of indicating that this version is incompatible with the Ito & Mester system? If someone clicked "mark heads" (because they saw accentAsHead in Con) when using the built-in I&M system, they would end up confused.

Something compatible with the I&M system would be "The head of a node is either its rightmost child of the highest category, unless the node's children are all ω's, in which case its head is the rightmost accented ω." I see no reason to implement anothter version of head-marking based on this, though we could.

We decided that I would expand the info and remove "(Japanese)" from beside "Right-headed".
