interesting problem, since i don;t think that this xetex sublevel is present 
now, i sthis really xetex specific? if not, just leave the xetex sublevel; 
alternatively, if these are special files,

        fonts/xetex/bitstream

more fits tds

this leads to file name clashes, so maybe it's better to cook up something, 
unless it are replacements, and the xetex path takes precedence

      xetex-color.sty

the recent tds/tex live changes kind of got rid of those etex, pdftex etc paths
