It’s an interesting time! To improve and speed up our work, I invite you and everybody else to give feedback on the latest developments around lookups and updates. Some links to start with:

I’ll be offline pretty often until end of June, so @all please bear with me if I won’t be that responsive.

as a (deep) lookup operator so far. Is that right?

Correct. The exact syntax (including key specifiers, which will be similar to XPath axis specifiers) is still subject to discussion, so we haven’t included it yet in our official release.

Thanks, as Michael Kay was playing at XMLPrague this morning with Saxon 13 and ?? on XDM maps and arrays I had hoped I could try some of that stuff out with BaseX but I understand that is all work in progress and therefore hard to include in some snapshot state in an official release.

So I will have to wait to use it until some later release.
