Construction of Attribute Values From Registered Primitives

The proposed function provides an exact specification of which values may validly appear within a document for a parameter.

An exact specification of a parameter's permitted values is declared using a tabular function, such as a Document Index (DOI) structured field, to describe the valid values that may be specified for a parameter. The table is pointed to by a structured field which identifies the parameter. For DOIs, this would be a Document Attribute (DOA) structured field. The DOA would define a parameter such as FIGURE_WIDTH. If FIGURE_WIDTH is constrained to be between 10 and 85 tenths of an inch, the DOI can explicitly record this restriction and all subsequently specified values for FIGURE_WIDTH can be verified to determine whether or not they satisfy this restriction.

The architecture registers the proper codes to represent values such as 0, 1, 8, 5 and other numbers, alphabetics, and special characters. These registered values appear in a Primitive Value Parameter of the table. A table may reference other tables using in this case a DOI Reference parameter.

A Table Index Type parameter is used to specify how to process the entries in the table. To specify values from 10 to 85 the table would have three entries. The first entry would specify concatenation in its Table Index Type parameter which means the resolved entry values are to be concatenated together in the same order as the table entries. The first table would use two DOI R...
