I think the error message is complaining about an error in your instance
document which is nothing to do with the schema - you have used the prefix
mml in the instance without declaring it in an
xmlns:mml="http://www.w3.org/1998/Math/MathML" declaration.

Having fixed that, to get the instance validated against the MathML schema
you then need to do two things:

(a) use xsl:import in your schema document to import the schema for the
MathML namespace

(b) use processContents="strict" on the xs:any element to ensure that any
MathML elements matching the wildcard are validated against their schema
