Re: [Saxon-JS 2] Creating a JSON object

Right, the attribute is a leftover from the Saxon-CE code... I found
this snippet somewhere, I think the intention is to be able to use the
attribute value template to inject values. But I can see that || in
XSLT 3 does pretty much the same.

This code is calling methods on a JS library which builds a SPARQL
query string in the end. It all works fine through ixsl:call(), it's
just the object creation that requires ixsl:eval().
