I believe this is one of the feature requests that were suggested here. 
It would be very useful if accessing fonts through pathnames were 
possible, like:
\font\caslonsc = "D:\fontslib\Adobe\ACaslonPro-Regular.otf:+smcp" at 16pt
\caslonc Text in small caps

I don't know if accessing glyphs through glyph IDs or glyph names is 
possible in XeTeX. However, in most OpenType fonts, each glyph is 
accessible through a combination of a Unicode codepoint of the "parent" 
glyph plus a set of OpenType Layout features. In many OpenType fonts, 
glyphs that are not default representations of Unicode characters have 
Private Unicode Area (PUA) codepoints.

referring to the Chuck Norris halloween costume he was wearing.
