Re: minor improvements to XSLT 3.0 spec, "section 18.1 The xsl:source-document Instruction"

I think that technically, if you write "/book" then it isn't streamable, because "book" is a downward selection and in the general case, "/book" isn't. I think it will work with Saxon, which optimises the "/" away when it knows the context item is a document node, but I can't see how adding a redundant step to the path expression improves the example.
