如何始终从W3C引用xml.xsd的最新版本？

Question

Many XML schemas I use reference xml.xsd eg thus:

<xs:import namespace="http://www.w3.org/XML/1998/namespace" schemaLocation="http://www.w3.org/2001/xml.xsd"/>

This schemaLocation value references a specific version of the XSD.

Is it possible to refer to the "the most recent version W3C's xml.xsd" rather than "this version" and going back to check for updates / aligning different schemas to the same version, etc.?

Answer 1

If you read the "Versioning policy for this schema document" section in that document, you will see that this policy is precisely what you ask for:

The schema document at that URI may however change in the future, in order to remain compatible with the latest version of XML Schema itself, or with the XML namespace itself. In other words, if the XML Schema or XML namespaces change, the version of this document at http://www.w3.org/2001/xml.xsd will change accordingly; the version at http://www.w3.org/2009/01/xml.xsd will not change.
