[xsl] is document('') mandatory for xslt1-conformant processor?

[Oleg Tkachenko <olegt@xxxxxxxxxxxxx>]

Hello!

As I understand xslt1 spec is somewhat ambiguous about document('') 
feature. Firstly it says: "An XSLT processor is not required to support 
any particular URI schemas". But some paragraphs below it says: "Note, 
that a zero-length URI reference is a reference to the document relative 
to which the URI reference is being resolved; thus document("") refers 
to the root node of the stylesheet;...".
So, is document('') mandatory or not?
I care about it particularly because I involved in developing a 
specialized xslt processor, which compiles stylesheets to some 
intermediate code and so have trouble to get source of xsl stylesheet.
