WikiMl: "WikiMl (for Wiki MarkupLanguage) is a non XML markup language similar to the formats used by WikiWikiWeb systems for user entry.

WikiMl does a fair attempt to be compatible by the common practices of WikiWikiWeb systems, however since there is not a complete compatibility and interoperability between these formats, it can't claim to be compatible with them either...

The goal behind the definition of this format as a MarkupLanguage is to take WikiMl out of the sphere of WikiWikiWeb systems to use it as a full class MarkupLanguage easy to edit and able to replace a subset of XHTML in XML based applications.

This looks cool; I need to look at this some more when I get time.
