Sorry, I was not precise. I meant all my annotations of TYPE "Word" are
linear and connected, so that

AG::CheckLinear $agId "Word"
AG::CheckConnected $agId "Word"

succeed in the current implementation.

I thought we were talking about the possibility to restricting the
sorting to certain annotation types, meaning that an AG may be connected
and disconnected at the same time, depending on what annotation type(s)
are viewed as 'relevant'? So that my Tool would only view a subset of
all annotation types as 'his/hers' and ignore the others, so that only
the relevant types have to meet the constraints imposed by my Tool.

I'd be happy to contribute as far as I am able to.
