I did append "/guidance" after "advice" to cover
other interpretations.  The introductory prose
says "The following trigger full standards mode:"
which I think one might reasonably interpret as
"guidance" if one wishes to trigger full standards
mode ...

I don't "want" to be; I am forced to be, because my co-developer
is still using deprecated combinations of elements and attributes.

Not sure how to interpret this last, but I don't want to "rely on
the difference", but rather "rely on full standards compliance".
