Jérôme > A*B = { <x,y> | x\in A /\ y\in B } > with the binding of two variables x and y. MathML as specified doesn't really give a good method of marking up this construction. Thank you for highlighting this deficiency. For MathML2 we now plan to deprecate the existing usage of set with _just_ a bound variable and a condition and instead make the set constructor take one or more bvar elements specifying bound variables (x and y in your example) a condition element specifying the predicate ( x\in A /\ y\in B here) and (new) the remaining child being an expression in the bound variables for constructing the elements of the set. <x,y> here. The current usage where the last expression is omitted, and the set ranges over the bound variable will be deprecated. (Note this is only a plan at present, we have to see how this would affect other parts of MathML, and existing MathML systems.) > 2) unlike many (but not all) other examples, the "Default rendering" > does not render the "Example". This was an existing issue item for us to bring all the default renderings into line with the examples. Thanks again for your comments, David
