I should have said what I'd propose.

1. Remove the second PrefixDecl term from the Query term, so there
is only one place prefixes are defined; before the ReportFormat term.

2. Change FromSelector to only allow URIs. Edit to be ::= QuotedURI
or alternatively, put it inside FromClause, delete FromSelector.

3. Define prefix/URI expansion to happen in the order they are given
in the syntax, with later prefixes overriding earlier ones.
