stage-code Stage Code for Standard Project Lifecycle

The @stage-code attribute on <release-version> identifies the development stage of the project that is developing the standard, as the standard passes through the various lifecycle stages to publication.

Usage/Remarks

Suggested values for @stage-code should be taken from the ISO document International Harmonized Stage Codes (https://www.iso.org/stage-codes.html). These values are 4 digit decimal numbers, two digits, the decimal, and two digits. The first two digits represent the main stage (for example, “00” for “Preliminary Stage”, “20” for “Proposal Stage”, “30” for “Committee Stage”, etc.) and the second two digits (following the decimal) contain the substage code for an appropriate lower-stage division of the main stage (for example. In the Preliminary Stage “20” for the “Project Proposal under review” and “99” for “Approval to ballot proposal for a new project”).
While these codes represent the stages in the life of the project that develops a standard, not the stages of the standard itself, such codes are often tracked to judge the maturity-level of the standard.
