My recollection would be that we said 'avoid' because we did not feel it was
reasonable to expect content completely to satisfy "do not use."  That
"do not use" would be interpreted as MUST NOT use in the RFC 2119 sense, 
"avoid" indicated a SHOULD NOT in the same terms.

If we go back and trace the discussion on layout tables, I believe this
interpretation should be borne out.  Not so clear we thought it through
in as much depth on deprecated features.

I haven't found conclusive proof, but at least at the April 13 meeting the
proposal to replace 'avoid' with the simpler "do not use" was considered.
The sense that 'avoid' indicates more room for discretion was raised, and
the proposed change failed to achieve a consensus either way.

  Minutes from 13 April Working Group Teleconference

Is there some way to trace from here through the change log for the issues list
to see if this issue were ever resolved at some point?

My answer to Pam would be threefold:

class="clarification personal">

a) yes, the language is meant to leave some room for discretion, for
deprecated features to be used where the option is [too difficult].

b) this is not a free ride; this means that you have to make a good faith
attempt to avoid the use of these features before claiming compliance.
Whether you have indeed made a good faith effort is something that would
require examination of the facts of the pages, and cannot be determined
simply by a clarification of the checkpoint.

c) the Working Group will attempt to clarify or interpret the guidelines
but cannot take on case-by-case reviews including the facts of a particular
