Subject: RE: [xri] Bug in pseudocode?

Yes, that’s right. For that reason we
should probably define what “x” means up front, before the pseudocode starts,
and then we can use “For Each X”. =Drummond From:

Behalf Of Gabe Wachob I think you are saying
that you need a Foreach X in Type, MediaType, Path, right? On Sun, Feb 24, 2008 at 10:39 PM, Drummond Reed <drummond.reed@cordance.net>

quite figure out the pseudocode here (in sec 13.6): [=Drummond] Gabe, good catch – nobody noticed that since we
added section 7 right at the end of the CD02 cycle, we needed to update all the
section references in the pseudocode (they are hand-coded references and not
bookmarks). Below is an update to the pseudocode text with all the
references updated. RE the Present.x and nodefault_x references you cite above,
the "x" just stands for "Type, Path, or Mediatype" as was defined
above – nobody thought we needed to redefine it. Maybe we need to take that
definition out of the previous FOR loop and put it at the very start so it's
clear it's a global definition? We just used "x" because it made the
code much more compact than calling out three separate loops, one for Type, one
for Path, and one for Mediatype. I'm wide open to your suggestions for how best to improve
this. =Drummond FOR
