The NISO STS document model may be used to describe many kinds of standards documents,
not just standards and adoptions of standards. It is a guiding principle of this Tag
Set that any standards document that can use the modeling rules for a standard
may be tagged according to this Tag Set. This <doc-type> element names the type of document, for example, a standard (standard
), a specification (spec
), or a technical report (tr
).
