[MathML3-last-call] Clarify how "symmetric" should be set by the Operator Dictionary

I like the compact form to list boolean valued properties of an operator 
in Appendix C. However, in the section that describes the format of 
operator dictionary entries, these rules are given in order to set their 
values:

"Boolean valued attributes such as stretchy are specified together in 
the final Properties column by listing the attribute name if its value 
should be set to true by the dictionary."

and "Any attribute not listed for some entry has its default value, 
which is given in parentheses in the table of attributes in Section 
3.2.5 Operator, Fence, Separator or Accent <mo>."

If I read this correctly, the "symmetric" property should be set to 
"true" when it is present and to its default value when it is not. But 
its default value is still "true" according to section 3.2.5.2.1 !
