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

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

Maybe you're passing a document-node() to your module?
Can you try with a double slash after your $doc, e.g. $doc//tei:teiHeader/tei:profileDesc/tei:particDesc/tei:person/tei:birth/text()
and/or make it explicit via
declare function bibl:dob($doc as document-node()) as element() {...}

Anyhow, I think we would need to see the whole files to be able to say more ...

All the best
Peter
