No.  Implementations are supposed to handle all valid library names
(i.e., anything
that's a list of symbols, whatever their content might be).  It might
be confusing
for the users though as there is no "standard" library-name->file-
name mapping.
(ikarus uses "srfi/%3a1.sls" for srfi 1 while mzscheme uses srfi/%
3A1.sls, note the
case difference which might just be an artifact of the case of the
string returned
by (number->string (char->integer #\:) 16) under the two
implementations)
