The spec currently says
"Any number of values can be given for notation separated by whitespace; all
of those given and understood by a MathML renderer should be rendered. For
example, notation="circle horizontalstrike" should result in circle around
the contents of menclose with a horizontal line through the contents. "

That seems pretty clear to me that all of the values should be rendered.  It
is maybe less clear that they should overlap, but the paragraphs that give
default spacing from the content, so that is pretty strongly implied just as
it is in the text above.  Is it really necessary to add something that say
they should overlap?
