In order to try to understand that, I have been looking at  
fontspec.sty and could not find any explicit call to a specific font  
file such as lmroman10-regular(.otf).

It seems fontspec calls by default the lmodern package with uses the  
standard way of calling fonts, as specified in ly1-lmr.fd for  
example, namely through TFM files such as texnansi-lmr10.tfm. But  
then I would have expected lm-texnansi.map to be used, which calls in  
turn lmr10.pfb.

Accordingly, I could not identify what specifies (i) use of OpenType  
font files instead of PFB font files and (ii) call of the font by  
file name instead of font name.

I think the problem is, simply, that I stopped following the detail  
of the evolutions of fontspec and XeTeX at some point, and now I'm a  
bit lost when anything doesn't work at first try. Thus it's probably  
best to just ignore my comments, and I'll refrain from making others  
until I find time (if ever) to look at things in detail.
