 ANSI ASC X3/J14 Technical Proposal  Page 1 of 1          90-752

 Title:    Compliance With Accepted Practice.

 Author:   Lawrence P. Forsley

 Abstract: Add a rational to the scope of work.

 Proposal:

 Proposals measured against accepted practice fall into one of four
 categories:

 1. Accepted practice is clear: e.g. DUP

 2. Accepted practice is conceptually clear, but there are code
 differences: e.g. VOCABULARY

 3. Accepted practice isn't conceptually clear and code differences
 abound: e.g.  vocabulary search order

 4. Accepted practice in the specific is upsurped by considerations in
 the general: e.g. POSTPONE, where accepted practice precluded a class of
 implementations, or, CATCH/THROW, where transportability takes
 precedense over lack of accepted practice.

 In category 1 we accept the proposal.

 In category 2. we acknowledge several accepted practices, and

    a) temporize, or
    b) arbitrarily choose one.

 In category 3, we leave it out of the standard.

 In category 4, we develop a new technique.

 Thus,
   We choose to do what is known, or
   we temporize those things we can't decide, or,
   we arbitrarily choose one of two or more existing practices, or,
   we develop a new technique to resolve and inconsistancy.

 Discussion:

 There is confusion regarding the seriousness of the commitment to the
 following accepted practice.  This rationale attempts to clarify the 4
 possibilities open to us in considering accepted practice.  That is,
 there are cases when we must diverge from accepted practice: when more
 than one practice is accepted, when an accepted practice is inconsistant
 with another accepted practices, or when other issues, such as
 transportability, take precedence over accepted practice.
