ANSI/NIST-ITL 1-2011 - UPDATE 2013 DRAFT VERSIONA system is conformant to this standard if it is capable of generating or using transactionsthat are morphologically, syntactically and semantically conformant to the requirements ofthis standard. Transactions shall consist of one Type-1 record and one or more of the Type-2to Type-99 records. For the structure of a transaction, see Section 5.1. For a description ofthe Record Types, see Section 5.3. Prior versions of the standard only required a Type-1record.2.2 Morphological 4 (Level 1) conformanceMorpohological conformance deals with the form and structure of the internal content andverifies data structures exist and have allowable values. Specifically, it checks for thestructure and value of each field, subfield and information item in a transaction.A transaction conforms morphologically to this standard if it satisfies all of the normativemorphological requirements related to its data structure and data values, as specifiedthroughout Section 7 Information associated with several records and Section 8 Recordtype specifications. If the system claims conformance with a particular encoding, then itshall satisfy the requirements of either Annex B: Traditional encoding or Annex C:NIEM-conformant encoding rules, as appropriate.Table 1 Excerpt from Table 24: Type-4 record layoutFieldNumberMnemonic Content Description CondcodeTypeCharacterMIn#Max#ValueConstraintsOccurrenceMIn#Max#4.004 FGPFRICTION RIDGEGENERALIZED POSITIONMNT=1X=1T=1X=30 < FGP < 15 orFGP = 255 integerSee Table 86 6The excerpt above is taken from Table 24 Type-4 record layout. Notice the “ValueConstraints” column.

Testing this type of conformance for Field 4.004 involvesverifying that the value for FGP is zero or that it is a positive integer less than orequal to 15 or that it is equal to 255. A value of 10 is conformant; however, a4[2013e>] Morphogological and Syntactical header labels were reversed in thesesections in the 2011 text. The explanatory text was correct. [
