Hi Ed--
You could do it that way, by using the "modify_tag"document callback to
attach a dlgitem callback to the "OK" button on the modify attributes
dialog.
You could also use the AOM to add an event listener to the document for
the DOMAttrModified event. That would let you take some action in the
event of a particular element having a particular attribute value set,
no matter how the change is made (via Modify Attributes dialog or via
script).
I think the examples in the customizer's guide should also be available
in the HTML portion of the Help Center, as well as the PDF. If you
decide to go with the ACL/Modify Atributes route, the OK button on the
Modify Attributes dialog has the ID of "OK".
