Hi Gunther,

Yes, this is a known issue in BaseX. Here is another example for two queries that should yield the same result (currently, the first one fails):

<e a="{1 instance of integer}" xmlns="http://www.w3.org/2001/XMLSchema"/>

<e xmlns="http://www.w3.org/2001/XMLSchema" a="{1 instance of integer}"/>

Thanks for reporting it; it’s just another hint that we should get this fixed.

All the best, Christian

The order of attributes, including namespace declaration attributes, in a direct element constructor is not significant. But while playing around I found that it makes a difference with BaseX for expressions that are embedded in an attribute.

So these two constructors produce different results, but I think it should be the same:

basex -q"<e xmlns='A'><e xmlns='B' a='{namespace-uri-for-prefix((),

<e/>)}'/></e>"

basex -q"<e xmlns='A'><e a='{namespace-uri-for-prefix((), <e/>)}'

xmlns='B'/></e>"

Tested on BaseX 8.4.1.

Best regards Gunther
