There is a difference of abstraction here that you seem to be confusing.

MathML is a vocabulary defined using XML to represent mathematical concepts in XML markup documents. XQuery is a language to query your vocabularies that are defined using XML. XQueryX is an XML representation of that language.

If you think that MathML can be used since it provides the same semantics for the mathematical operations and can be used in the context of an XQuery expression tree, feel free to write a proposal (or at least some detailed examples).

Also please note:
RDF is a semantic EER model that represents graph structures. It has an XML serialization, that is not very well suited for writing queries that operate on the semantic abstraction level of RDF. Thus, they decided to define their own query language (whether that was good or bad, I don't comment on).

Best regards
Michael
