Non-Marking Characters

Hi,

thank you for previous answer,

Another problem:
In MathML 2 specification to Non-Marking Characters (
http://www.w3.org/TR/2001/REC-MathML2-20010221/chapter6.html)
we have a list of Whitespace entities: 	, 
, &Space;,
 , ...

But this list is not in the new specification for MathML 3 at 7.6
Non-Marking Characters (http://www.w3.org/TR/MathML3/chapter7.html)

*This list is the list of entities accepted to be displayed in a mtext
element ?*
If not, do you have a list of accepted "renderable whitespace" ?
