Documentation:
Used by `nxml-glyph-set-functions' to return set of glyphs in a FACE.
This should dynamically bound by any function that runs
`nxml-glyph-set-functions'. The value must be either nil representing an
empty set or a vector. Each member of the vector is either a single
integer or a cons (FIRST . LAST) representing the range of integers
from FIRST to LAST. An integer represents a glyph with that Unicode
code-point. The vector must be ordered.
