19.3.1 Syntax of Logical Pathname Namestrings

The syntax of a logical pathname namestring is as follows. (Note that unlike many notational descriptions in this document, this is a syntactic description of character sequences, not a structural description of objects.)

logical-pathname::= [host host-marker]  
                    [relative-directory-marker] {directory directory-marker}*  
                    [name] [type-marker type [version-marker version]] 

host::= word 

directory::= word | wildcard-word | wild-inferiors-word 

name::= word | wildcard-word 

type::= word | wildcard-word 

version::= pos-int | newest-word | wildcard-version 

host-marker---a colon.

relative-directory-marker---a semicolon.
