Thank you for pointing at Google decision deprecating XSLT 1.0. Proposed migration options have not already been tested for XSLTForms.

Applying the XSLT 1.0 stylesheet at server side is, of course, still possible depending on server capabilities.

Latest XSLTForms releases allow authors to directly insert XForms-like custom elements in HTML pages without needing XSLT 1.0 support at browser side.

Because XPath parsing has already been rewritten in Javascript in latest XSLTForms releases, the resulting lighter XSLT 1.0 stylesheet might also be rewritten in Javascript. For example, it might, then, be possible to mimic the IFRAME HTML element with a custom element to load XHTML+XForms as HTML+Javascript.

What would be your own use cases for migration?

Kind regards,
