sequence of nodes, starting from ndTokenFirst, that can be grouped into a run. For
example, nodes A and B can be grouped together into the same run iff they have the same
props.
To accomplish this grouping, we want to find the next sibling to ndTokenFirst that shouldn't be
included in the run of text. We do this by counting the number of elements that precede the first
such element that doesn't belong. The xpath that accomplishes this is below.
Count the number of siblings the precede the first element after ndTokenFirst that shouldn't belong.
count($ndTokenFirst/following-sibling::*[ . . . ][1]/preceding-sibling::*)
Now, the hard part to this is what is represented by the '. . .' above. This conditional expression is
defining what elements *don't* belong to the current run. The conditions are as follows:
The element is not a token element (mi, mn, mo, ms, or mtext)
or
The token element contains a glyph child (this is handled separately).
or
The token is an mtext and the run didn't start with an mtext, or the token isn't an mtext and the run started
with an mtext. We do this check because mtext transforms into an omml m:nor property, and thus, these mtext
token elements need to be grouped separately from other token elements.
// We do an or not( . . . ), because it was easier to define what token elements match than how they don't match.
// Thus, this inner '. . .' defines how token attributes equate to one another. We add the 'not' outside of to accomplish
// the goal of the outer '. . .', which is the find the next element that *doesn't* match.

There are two possible omml constructs that an mtable can become: a matrix or
an equation array.
Because omml has no generic table construct, the omml matrix is the best approximate
for a mathml table.
Our equation array transformation is very simple. The main goal of this transform is to
allow roundtripping omml eq arrays through mathml. The template ProcessEqArrayRow was never
intended to account for many of the alignment flexibilities that are present in mathml like
using the alig attribute, using alignmark attribute in token elements, etc.
The restrictions on this transform require <malignmark> and <maligngroup> elements to be outside of
any non-grouping mathml elements (that is, mrow and mstyle). Moreover, these elements cannot be the children of
mrows that represent linear fractions or functions. Also, <malignmark> cannot be a child
of token attributes.
