Multiple boundary tags in meshmode export

FWIW, since firedrakeproject/firedrake#2007 entities can be marked with multiple tags and it all works. After building the plex, create a "Face Sets" label (or if you don't like that literal, a firedrake.cython.dmcommon.FACE_SETS_LABEL) (or CELL_SETS_LABEL for cells) and mark the points.

@wence- Thanks for the heads-up!

The examples in utility meshes seem to only tag each face label with one tag (e.g. plex.setLabelValue(FACE_SETS_LABEL, face_id, label_id)). Are there any examples of tagging with multiple tags?

I don't think so. You can make a gmsh mesh that does multiple tags. Or just copy one of those functions and do multiple marking.
