The document’s revision number or version is assigned to the built-in
revnumberattribute. When assigned using the revision line, the version must contain at least one number, and, if it isn’t followed by a date or remark, it must begin with the letter v (e.g.,
v7.0.6). Any letters or symbols preceding the number, including v, are dropped when the document is rendered. If
revnumberis set with an attribute entry, it doesn’t have to contain a number and the entire value is displayed in the rendered document.
The date the revision was completed is assigned to the built-in
revdateattribute. If the date is assigned using the revision line, it must be separated from the version by a comma (e.g.,
78.1, 2020-10-10). The date can contain letters, numbers, symbols, and attribute references.
Remarks about the revision of the document are assigned to the built-in
revremarkattribute. The remark must be separated by a colon (
:) from the version or revision date when assigned using the revision line.
