Hello,

I would like to report two errors in MathML Spec.

http://www.w3.org/TR/2003/REC-MathML2-20031021/

First error

There are three items in 3.2.5.8.3 Horizontal Stretching Rules such as:
List Item One
If a stretchy operator, or an embellished stretchy operator, is a direct sub-expression of an munder, mover, or munderover element, or if it is the sole direct sub-expression of an mtd element in some column of a table (see mtable), then it, or the mo element at its core, should stretch to cover the width of the other direct sub-expressions in the given element (or in the same table column), given the constraints mentioned above. 

List Item Two
If a stretchy operator is a direct sub-expression of an munder, mover, or munderover element, or if it is the sole direct sub-expression of an mtd element in some column of a table, then it should stretch to cover the width of the other direct sub-expressions in the given element (or in the same table column), given the constraints mentioned above. 

List Item Three
In the case of an embellished stretchy operator, the preceding rule applies to the stretchy operator at its core. 

List Item One equals to List Item Two plus List Item Three. List Item One or set of Two and Three
should be deleted.


Second Error

Example rendering result in 3.3.2.2 Attributes of mfrac.

image/f3007.gif is not a correct presentation of the same example of markup.

I hope they will be revised in a future.
