Recommendation Issues
- (N choose k) DTDs
- ... must be hand-crafted each time
- Wrapper Elements
- ... who decides where math goes inside html ?
- (general best practice, not math-specific)
- Schemas without a character entity mechanism
- Can use DTD reference + Schema reference
- ... but this does not work for embedded math fragments
- MIME types vs namespaces
- ... what is the MIME type of an XHTML+SVG+MathML document ?
