Dear BaseX team,

I encountered a strange phenomenon: after loading a document into the database (using db:create), ordinary retrieval yields a phantom with distorted namespaces, like this:

<Accommodation xmlns="http://otds-group.org/otds">
  <Availabilities xmlns="" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://otds-group.org/otds" Key="1Z">
    <Availability xmlns="" xmlns="http://otds-group.org/otds" Key="1Z" StartDate="2013-05-01" EndDate="2013-10-31">
      <DefaultDayState xmlns="" xmlns="http://otds-group.org/otds">
        <Open xmlns="" xmlns="http://otds-group.org/otds"/>
      </DefaultDayState>
    </Availability>

...

Note the xmlns="", side by side with xmlns="...".

This is the query:

let $c := * return element {node-name($c)} {$c/*:Availabilities}  

And this is the (correct) result I obtain if I use as input not the uploaded document, but the original file:

<Accommodation xmlns="http://otds-group.org/otds">
  <Availabilities xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" Key="1Z">
    <Availability Key="1Z" StartDate="2013-05-01" EndDate="2013-10-31">
      <DefaultDayState>
        <Open/>
      </DefaultDayState>
    </Availability>
...

I wanted to reproduce the problem with a minimal input document, but then the error did not occur.

The document producing the error has 286 KB.

One more remark: after droping all databases and repeating the exercise, the problem still remained.

Kind regards,

Hans-Juergen

PS: If a team member would like to receive the input file, I would send it to him or her directly.
