Is that how attribute lookup works? I.e., given a path, all attributes 
are collected?

Isn't it more like: Here we are interested in the "eol" attribute of 
this file named "a.foo". And the lookup would find the first line that 
says "eol=crlf". Elsewhere, we are interested in the "binary" attribute 
of the file named "a.foo", and lookup would find the second line that 
sets the "binary" attribute. And again elsewhere, we ask for the "text" 
attribute, and we find the last line that sets the "text" property.

Am I totally off track?
