Thank you for you message but as I mentioned when you sent the same
wording to the HTML WG bugzilla, your comments are not at all clear, I'm
not sure what changes you would like us to make.

Taking them out of order.

The subject line refers to Content MathML but you comment that
mglyph (which is not a content mathml element) is not in "the
navigation" by which I assume you mean the table of contnts?

http://www.w3.org/Math/draft-spec/chapter3.html

http://www.w3.org/Math/draft-spec/chapter3.html#presm.mglyph

As to your main point about content elements not being in the table of
contents, the main set that do not have their own section are the
trigonometric functions which are all listed under

4.4.7.1 Common trigonometric functions
http://www.w3.org/Math/draft-spec/chapter4.html#contm.sin

All these elements operate in exactly the same way and it would serve no
purpose to make the chapter significantly longer duplicating the
description for each one under a separate heading.

If however you want to mechanically generate links back from an instance
of a particular function to the description of the element in the spec,
the anchors are all there, so for example for <sin/> you can link to

http://www.w3.org/Math/draft-spec/chapter4.html#contm.sin

I hope that clarifies thing, if there are any specific changes that you
think we should make, please do post again.

David
