Any plans to support the below in Virtuoso?

Please note that the cited document reports:

This document is a draft of a potential specification. It has no official standing of any kind and does not represent the support or consensus of any standards organization.

Also note that, although it borrows from W3C stylesheets, and so resembles W3C documents, it is not a W3C document of any kind.

Further, note that "latest published version" is dated 2024-06-04, though the "latest editor's draft" is dated 2025-04-21.

OpenLink Software does not typically implement functionality until there is a significantly advanced specification, like a W3C Candidate Recommendation (CR) or Proposed Recommendation (PR), if not a full W3C Technical Recommendation (TR).

That said, if there was a significant business case, such as a customer needing such functionality that might be willing to pay for custom development, which would obviously require some redirection of our development staff away from our existing priorities, we could invest some time in exploring what such an implementation would require of us, and hence quote the cost for such custom development.

Fair enough, thanks for the response @TallTed ! I've have been trying out the CDT support that was added to Apache Jena in the last version to get a feel for it. I tend to use Virtuoso for my large-scale data, so I thought I would ask.
