Schemas should specify this attribute.

Implementations shall report the value or the absence of this attribute at user option.

Declaration

element schema {
        attribute id { xsd:ID }?,
        rich,
        attribute schemaVersion { non-empty-string }?,
        attribute schematronEdition { non-empty-string }?,
        attribute defaultPhase { xsd:IDREF }?,
        attribute queryBinding { non-empty-string }?,
        (foreign
         & (inclusion | extends)*
         & (title?, ns*, p*, param*, let*, phase*, abstract-rules*, (rule-set|pattern)+, p*, diagnostics?, properties?))

Proposal for proper language versioning system

Sample usage

Example 5. schematronEdition attribute

<sch:schema schematronEdition='2025'>
  <sch:pattern>
    <sch:rule context='*'>
      <sch:report test='true()'><sch:name/></sch:report>
    </sch:rule>
  </sch:pattern>
</sch:schema>

The implementation XQS for example implements this feature using a command-line (and API) option, report-edition. If this is switched on, the application reports an empty schema element, including any schematronEdition attribute, as the first item returned, e.g.

<schema xmlns='http://purl.oclc.org/dsdl/schematron' schematronEdition='2025'/>

Commentary

This attribute provides a mechanism to differentiate the version of schema markup used without changing the namespace for schemas generally, in the interests of backward compatibility.
