Solid

Hi guys,

I'm using SOLID to figure out and define the structure of a Toolbox lexicon. This morning I ran into an issue with the three possible choices for defining a marker's place in the structure. The marker being defined is "ph", and its parent marker is "oc"

If I say "ph can appear under oc (x) Once", I get 16 errors.
In reviewing the errors it's clear that they're all just cases of multiple ph fields, side by side with no intervening markers.

So then I say "ph can appear under oc (x) One or more times together" and run a recheck, expecting all the errors to be gone now. But instead I find that it's jumped from 16 to 53.

Finally, to get rid of all errors I find it necessary to go to the third option "ph can appear under oc (x) One or more times with intervening markers". This works, but is more permissive than should be needed, since there are no cases of intervening markers between ph fields.

I'm guessing that this inconsistency has to do with a factor that's been left unmentioned - whether or not there are other markers between the marker and its parent. Expanding on the definitions of the three options, here's how I suspect they're actually operating:

1) Just once, with or w/o preceding markers
2) One or more times together, no intervening markers, no preceding markers
3) One or more times, with or w/o intervening markers, with or w/o preceding markers

It seems that the second option is disallowing any markers intervening between the first child marker and the parent as well as between child markers, while the first and third options have no such constraint.

The behavior I'd like to see for 2 is:
2) One or more times together, no intervening markers, with or w/o preceding markers

I don't know whether it might be important sometimes to also specify that preceding markers aren't allowed. If this is needed, maybe it could be included as a separate option, rather than lumping it together with intervening markers.
