New draft, 2 Apr 2008

I merged Henry's changes, amended per my understanding of our discussions
last week. The new draft is in the usual place /XML/XProc/docs/langspec.html
dated 2 Apr because, well, because I refuse to date a draft 1 Apr :-)

                                        Be seeing you,
                                          norm
