Dear Mike,

As an editor of the spec, I would love to understand why so many readers
of the spec seem to have difficulty finding this section, or discovering
that the XPath "and" and "or" operators are written "and" and "or". If
you could explain what your strategy was for finding the information,
and how you came to miss it, I would be most interested to see what we
can learn.

I'm guessing people are making more or less educated guesses, and not reading the spec or even seeking out resources such as these:

To make things worse, it seems that the best preparation for learning XSLT is whatever the preparation is that prepares one for anything, since one soon learns (or doesn't) that this is an area where the more "educated" a guess is, the less likely it is to be correct.

As a distraction to allow me to procrastinate on more important things, I have been giving myself a remedial course on the basic CS I missed in school, learning about designing logic gates. The analogies with XSLT are interesting. Wiring up a circuit isn't really programming either. (Or I suppose it is, depending on what one means by "programming".)

Cheers,
Wendell
