mathml-version MathML Version

Which version of MathML is used by the tag set for this document?

Usage/Remarks

All four versions of STS include the definition of a MathML variant. But if no version of MathML is used to tag documents in this particular tag set, this attribute should not be used.
Related Attributes
Several attributes on the <processing-meta> element describe the tag set version choices more fully than the @dtd-version attribute alone:

Which table model is used by the tag set for this document? (e.g., “xhtml” or “oasis”)
Which version of MathML is used by the tag set for this document? (e.g., “3.0” or “2.0”)
Are the terms for this standard described by TBX or by <term-display>?
A list of the (possibly many) ways mathematical expressions may be represented in this document (e.g., both MathML and TeX [“mathml tex”])
OPTIONAL on element: <processing-meta>
