MathML DTD: mstyle attributes and attribute actiontype (maction)

Hi

I' m missing the bevelled (mfrac) and the side (mtable)
attributes on the mstyle element.

Not really missing (:-) but also not present on the mstyle element:
the notation (menclose) attribute.


<!ATTLIST %mstyle.qname;  
      %MATHML.Common.attrib;
      %att-fontinfo;
      %att-opinfo;
      %att-lquote;
      %att-rquote;
      %att-linethickness;
      %att-scriptlevel;
      %att-scriptsizemultiplier;
      %att-scriptminsize;
      %att-background;
      %att-veryverythinmathspace;
      %att-verythinmathspace;
      %att-thinmathspace;
      %att-mediummathspace;
      %att-thickmathspace;
      %att-verythickmathspace;
      %att-veryverythickmathspace;
      %att-open;
      %att-close;
      %att-separators;
      %att-subscriptshift;
      %att-superscriptshift;
      %att-accentunder;
      %att-tableinfo;
      %att-rowspan;
      %att-columnspan;
      %att-edge;
      %att-actiontype;
      %att-selection;

I think the actiontype attribute (maction) in contrast must 
not be in the mstyle element because it's defined as a 
required attribute in the recommendation.
[REC-MathML 3.6.6.1]
So it should also be defined with the keyword REQUIRED
in the DTD?

<!ENTITY % att-actiontype          
     "actiontype   CDATA                    #IMPLIED" >
