Re: document() question

["G. Ken Holman" <gkholman@xxxxxxxxxxxxxxxxxxxx>]

Sorry folks, I got hot and heavy with my cutting and pasting and made an 
assertion in the comment of one of my files that isn't true.  I found this 
while working on the revisions to my training material.

At 99/09/16 07:10 -0700, I wrote:

Actually, you can use that, what you cannot use is:

    document("")/id($id)/*

... because the id() function can only be used alone or at the start of a 
location path, not *in* a location path.  When I did the global cut and 
paste of id($id) to be /Book[@id=$id], I didn't notice the comment had also 
changed.

I've attached an example below of what I said couldn't be done.  The 
document() function can be at the start of any valid location path.

Sorry if this was misleading earlier.
