Hi Chris,
No, that is not the correct assessment.  8^)
The prefix string does not matter, all that matters in the stylesheet is 
that there is a prefix in the match attribute, and it is assigned to the 
mathml namespace name http://www.w3.org/1998/Math/MathML using the xmlns 
attribute.  That assignment can be done on the root element of the 
stylesheet so the namespace scope is the entire stylesheet, or in the 
individual stylesheet elements as is done here.

Your document can use a different prefix, or use the default namespace, as 
long as the namespace name is assigned.  The above template will match on 
all of these  elements in your document:

<m:mml xmlns:m="http://www.w3.org/1998/Math/MathML";>

<math:mml xmlns:math="http://www.w3.org/1998/Math/MathML";>

<bob:mml xmlns:bob="http://www.w3.org/1998/Math/MathML";>

<mml xmlns="http://www.w3.org/1998/Math/MathML";>

It will *not* match on <mml:mml> if the namespace prefix mml: is not 
assigned to the namespace name.

Hope that helps.
