Re: [eXist-TEIXML] passing arguments to XQuery functions

[Peter S. <st...@we...>]

Ok, that's been a hard one! But it's always about namespaces ;-)
The TEI namespace declaration in your module has a superfluous trailing slash.

By the way, I tried on eXist 1.4.1 where the inserted "p" node (from the bibl module) will have an empty namespace declaration in the result. You can avoid this by declaring a default namespace (both in your module and the main query and hence remove the namespace from your root html element):
declare default element namespace "http://www.w3.org/1999/xhtml";

All the best

The result in the webpage is that I see the separator ' - ' but no values for date of birth or death, which also suggests that $doc doesn't make it to the function.
