specification.

References in document (e.g. page, clause, figure and/or table numbers):  

Clause 9.5.4.6.

Annex I, table 14, row T.14.5.

10

Nature of defect (complete, concise explanation of the perceived problem):
 
The rules for profiles in clause 9 and annex I address length limits for data type SF (string fixed) when it occurs standalone within an element, and when it occurs within data of type D (data record).  However, the case of SF within data of type SDR (Structured Data Record) is not addressed.  SDR is the Version 3 improvement on and replacement of the Version 1 data type D.  The rules that apply for SF within D should also apply for SF within SDR.

11

Solution proposed by the submitter (optional): 

In clause 9.5.4.6, replace the paragraph (4^th pgph) beginning, “one for the group of elements with data type D…” as follows:

One for the group of elements with either data type SDR parameters which contain type SF data within the SDR parameter, or data type D parameters which contain SF data in the D parameter, in the case that the D parameter uses SDR formatting. 

In clause 9.5.4.6, remove FONT PROPERTIES from the list titled “Type SF Parameters” and insert it into the list titled “SF data within SDR parameters”.  Add APPLICATION STRUCTURE ATTRIBUTE to the list titled “SF data within SDR parameters”.  

In Annex I, table 14, row T.14.5, change the two occurrences of “for type SF within type D” to “for type SF within type D and within type SDR”.  (One occurrence is in the column “Specifications – PPF” and the other is in the column “Specifications – Model Profile”.)

Amend the standard as proposed above.
