Many thanks Evan. Looks like MicroXSD needs a bit more added to it then. I'll have to add simpleContent, extension and extension/@base for the bare bones functionality of data-typed elements which have attributes (even with or without child elements). To do this I might have to rethink my versioning or do that ugly trick and have a version 2012 in 2011! :-) As for RNG, I guess that gets decided by your toolset. If it were ever the case that say C# and SQL Server (my tools of trade) supported it maybe I'd switch. For now I'd guess a majority or near majority of web developers have to stick with W3C XML Schema so for them a subset of it like MicroXSD might be more pertinent to their work than a subset of RelaxNG. I imagine that picture might not change, for a long time at least. Many thanks though.
