Path component parameters are defined in the URI standard, but (AFAIK) do not 
exist in any POSIX standard-- nor does Linux itself provide support for URIs, 
as far as I am aware.

The URI RFC, while it does not define the application of parameters in file 
URIs, does define that "The parameters are not significant to the parsing of 
relative references.", which I read as meaning that "..;foo/bar" acts the 
same as "../bar". Following this logic, it would seem the "proper" thing to 
do in a file URI is to ignore unrecognized parameters and map my example 
to /etc/config/some.conf
