That's acceptable to me too. Initially I had a hierarchical method:

frame: seqs [
       info: "Select sequences"
       sequence: sequencea [ ..... ]

This was easy for me to parse, but I guess it completely breaks the normal ACD 
structure :-} Hence my other suggested change.

Missing endgroups wouldn't make it hard to parse (for me). A new group just
appends on to the existing 'path' and the endgroup pops it off. I guess you'd
disallow the following case:

group: g1 [...]
group: g2 [...]
endgroup: g1
endgroup: g2

If so, then we do not need to specify which group is being ended.

For generating HTML this is probably important. For my own work it doesn't
matter as the order of items in a dialogue does not need to be the same as the 
order of tcl code used to generate the items.
