*In this context, full support applies to the contents type as a whole; it does not imply the support of all document types or all possible values of the parameters (maximum-string-length, universal-class, and string-significance) that further define the contents type.
Document Types
Table 4-5 identifies the FTAM document types that the Compaq responder supports and provides all supported values for associated contents-type parameters. The parameter values listed here are those directly supported; for information on the default values of these parameter values, see Table 4-7, later in this section.
Document types can be simplified to other document types with simpler structures. Simplification is the process of reading a file of a specific document type as a simpler document type. Relaxations—specifications that change the parameter values of a document type—are not permitted by Compaq FTAM. For more information on simplification and relaxation, see the subsection “Contents-Type Attribute,” later in this section.
The NBS-9 parameter value < filename > shown in Table 4-5 is the syntax notation for representing the value of a bit string. In this case, only the filename attribute bit is set.
