I prefer DJ's color of bike shed for its syntactic similarity to names
paces in certain programing languages.

The idea is solid, and would be nice to see.

Ideally, backends should be able to communicate a list of attributes they
consume as a means to help populate lists in the gui (if we ever get to the
point where there is enough "project" concept to determine at schematic
capture time what backend(s) the user is targeting.) A configuration file
entry for target backends might be enough.

PCB already uses namespaces in its attributes, but using two colons:

"The target specified to be built is the first of these that apply:

 @itemize @bullet

 @item
 The target specified by an @code{import::target} attribute.

 @item
 The output file specified by an @code{import::outfile} attribute."
