Lennert,

the locspecs you propose seem ok to me (I am not sure whether this was what you were asking). Some comments:

We always default overrun to "error". Also, you could use an axis with measurement units of type "character" (or even "word") as well to express the selection.

The simple video video prototype we use bases its anchor definition on "frame" as the type of an axis. This is somewhat different to the type "seconds" that you are using (frames per second can differ).

This is an interesting one as it seems that you are using one axis to express a coordinate location (by using "pairs"). I could imagine that you could use two axis as well, one for the rows and one for the columns.

BTW: a few element types were missing in the DTD. I have updated it (see http://www.mmrg.ecs.soton.ac.uk/~sr/ohs/ohpxml/Darmstadt.dtd).

Cheers,

Sigi
