Currently, when "include classes" is checked, the HTML export creates "id" values for Object styles tags.

This would be more useful if there was a way to define the "id" value, but there seems to be no way to do that. I assume the "Object Export Options" under the EPUB/html tab would be the natural spot, or also in the Object Style as a global control.

Also, an option to turn off the "id" and still export the class would be ideal.

Attached is a screenshot of the the id values in a sample export.
