Zarella Rendon, an xmLP developer, spoke about xmLP at the Extreme Markup Languages 2002 conference in Montral, Canada (http://www.extrememarkup.com/extreme/). The presentation, "xmLP - a Literate Programming Tool for XML & Text", is now available at the xmLP site at SourceForge (http://xmlp.sourceforge.net/2002/extreme/index.html). Note that the talk describes xmLP 1.1, which is still under development, but nearing release.
Version 1.0 of xmLP, a literate programming tool for XML, has been posted on Sourceforge. See
