Attributes, I take it.

 

If your namespaces are sane, then QiC aren't a special problem.

I also think that "healthy neurotic" documents, which don't use prefixes and just change the default namespaces as needed, are a reasonable second to sane documents.  They don't allow arbitrary movement, and they don't work if multiple namespaces are used in scattered ways, but if they are used primarily at document component boundaries, they are tolerable.  If the MicroXML CG hadn't decided to eliminate namespaces altogether, I could easily have lived with this style.  Liam's automatic namespaces fit with this style.

Not to be confused with Jams O'Donnell notation.
