Biosequence Markup Language ( BMSL )
That is a nice summary of the capabilities and possibilities offered by
XML. Some work in this area has already been done. For more
information on the Biosequence Markup Language (BSML)
see the WWW page of Visual Genomics Inc. at
http://www.visualgenomics.com/bsml/index.html
A BSML browser and examples are available for download.
What is not currently clear to me is whether a given markup language
must to be approved by the WWW consortium, the Math markup
language 1.0 (
http://www.w3.org/Math/) has been released as
a W3C recommendation.
