Question on fragment identifier

Hi TC folks,

 

In the xliff 2.0 spec, the following constraints are given on construction of fragment identifiers:

 

·        
A fragment identifier MUST match the following format:

<_expression_>      ::= "#" ["/"] <selector> {<selectorSeparator> <selector>}

<selector>        ::= [<prefix> <prefixSeparator>] <id>

<prefix>          ::= NMTOKEN

<id>              ::= NMTOKEN

<prefixSeparator> ::= "="

<selectorSeparator>  ::= "/"

 

Is [“/”] to be interpreted as optional depending on whether the implementer wishes the fragment identifier to be relative or absolute?

 

For instance, are these two essentially equivalent?

 

#f=f1/u=u1/1

#/f=f1/u=u1/1

 

Only the first one is relative and the second is absolute? Which in the case of file is the same.

 

Thanks,

Ryan
