So the final version of the WCAG Samurai errata to WCAG1.0 was published yesterday, and it all seems eminently sensible to me.

The only correction I don’t understand at the moment is this one, under Guideline 10:

Do not add non-link, printable characters (surrounded by spaces or not) between adjacent links unless the semantics of the document naturally would include such characters.

As I understand it, that means don’t do this:

A | B

Does anyone know what the reasoning is behind this decision? (I’m sure it makes sense, I’d just like to understand why.)
