I'm not sure that's true.  The only reference to this I found
was in 4.13.1, which indicates a possible future direction for
evolution of the standard, as a warning to users and implementors.
That doesn't keep them from using is[a-z]* functions now, although
if one does so he may have to change his code later to conform to
a future revision of the standard.
