Is next <m:apply> <m:mo>≫</m:mo> <!-- put entity for the operator here --> <m:ci>x</m:ci> <m:cn>0</m:cn> </m:apply> recommended by certain tutorial on content MathML valid? I think is not because violates 5.2.2 Combinations that are prohibited. I find the spec really confusing for next case <mml:apply> <mml:ci definitionURL="" encoding="">Equilibrium</mml:ci> <mml:apply> <mml:times definitionURL="" encoding=""/> <mml:cn type="integer" base="10" definitionURL="" encoding="">2</mml:cn> <mml:apply> ... It is true that ci can be used for definition of operators and can be used as first child, but I assume part of the spec that matters are 4.2.2.1 Tokens: The csymbol element, or "content symbol" is used to construct a symbol whose semantics are not part of the core content elements provided by MathML, but defined outside of the MathML specification. also 4.4.2.3.1 Discussion: In MathML 1.0, fn was also the primary mechanism used to extend the collection of "known" mathematical functions. The fn element has been deprecated. To extend the collection of known mathematical functions without using the fn element, use the more generally applicable csymbol element or use a declare in conjunction with a lambda expression. and first child would be a csymbol. Am i wrong? On any case maybe may be useful when preparing next MathML 3 spec.Received on Friday, 24 November 2006 13:54:43 UTC
