I think the intention of the spec writers was to make that a problem for
the container implementors, not for the tag handler developer.

>From s.10.1.1:

"Note that since there are no guarantees on the state of the properties,
a
tag handler that had some optional properties set can only be reused if
those
properties are set to a new (known) value. This means that tag handlers
can
only be reused within the same 'AttSet' (set of attributes that have
been set)."
