Ambiguous abbreviations

Both letters and symbols can have multiple meanings dependent on context. Though we have instructed the vendors in a few of these contexts, in most cases we will have to deal with contextually governed interpretation of symbols at the review stage, if at all.

Our developing policy on this matter, based on expedience, has not and probably will not be consistent. Is a symbol a particular shape or set of shapes? a meaning or set of meanings? etc. Expedience dictates that in most cases we regard a symbol as a shape rather than as a significance or equivalence, but we may wish to make some exceptions. In particular, if we are sure that a given sign is being used to mean something particular, especially something other than it usually stands for; and if we can isolate the context; then we may want to capture the same shape in different ways.
