Question about Token elements

Hi,

In the specification there is:
*"With the exception of the empty
mspace<http://www.w3.org/TR/MathML3/chapter3.html#presm.mspace>element,
token elements can contain any sequence of zero or more Unicode characters,
or mglyph <http://www.w3.org/TR/MathML3/chapter3.html#presm.mglyph> or
malignmark elements."*
*
*
*A token element can have any combination of accepted elements ?*

Ex: I know I can have:
*<mi>abc</mi>*
or
*<mi><mglyph src="..." ... /></mi>*

but could I have mixed elements ?
*<mi>abc<mglyph src="..." ... />def<mglyph src="..." ... />...</mi>*
