Nexus is actually an extensible format so almost anything could be included.

Unfortunately there is still doesn't seem to be an online description of Nexus, though the standard was printed in the journal Taxon a couple of years ago.

Are you sure? I thought it was Systematic Botany.

Actually you're both wrong <G>. The formal description of the NEXUS format was in Systematic Biology.

The full citation is:

Maddison, D.R., Swofford, D.L. and W.P. Maddison. 1997. NEXUS: An extensible file format for systematic information. Syst. Biol. 46(4):590-621.

For what it's worth, the paper itself refers to a Web site (http://phylogeny.arizona.edu/nexus/nexus.html) for "additions and proposed additions to the format", but nothing seems to have been placed there, as yet (though the site does provide "pseudo-code" for a NEXUS parser).
