Multiple epub:type roles for a file in landmarks nav

In a thread in the EPUB forum, Can a file have multiple semantic tags?, after it was determined that such is possible, came this post:

I have been wrestling with this for a while and still am not sure the way to handle it best in Sigil. Perhaps a set of clips just for adding epub:type attributes to any user selected tag. Even at the file level with landmarks, Sigil keeps it to one, not multiple elements.

Ideas welcome on how to make all of the semantic setting easier for users outside of just the landmarks.

Of course, Access-Aide would have to be updated to handle multiple space delimited attribute values for epub:type and then to produce multiple attribute values for the aria role attribute as well.

I assume aria roles can have more than one attribute value as well.

May I suggest a UI enhancement for the Add Semantic Property dialog box: Instead of a “select one then click OK” list, how about a list of check-boxes? Easy way to indicate that more than one is possible, and also a clear way to see which properties are set on a file.
