Does anybody know if more than one id value can be assigned to a custom
button control within the customUI?
In other words, for the same button element can the idQ, id, idMso
attributes all have a value assigned?

SOLVED: If you turn on 'Show add-in user interface errors', id and idQ
attributes are mutally exclusive.

If both attributtes are used on a control element you will recieve the
following error:
Error Code 0x80004005
Mutually exclusive attributes 'id' and 'idQ' are specified.
