Hi,
for a class on XQuery someone wrote a simple XSchema from scratch and a sample instance. Both get evaluated for example by http://apps.gotdotnet.com/xmltools/xsdvalidator/; the Schema can be opened with the Tamino Schema Editor, validated and defined for a new database.

It is even possible to insert data to the database, but: I ran into problems querying the data.
A simple query like:
for $a in input() return $a
or X-Query for /
works fine, but anything more complicated results in an illegal cursor position or something like that. This is especially true for XPath expressions, however easy they are (yes, I checked spelling, etc. )

I can’t see any reason for that, but maybe someone of you will see it. Maybe it has something to do with self-defined (complex) data types? I never did this before, as all my other databases were based on a DTD and not on XSchema.

See Schema below and sample instance (no, that is not an actual person, just sample data).

I guess you selected “addressList” as doctype before defining the schema to Tamino. For me the schema looks alright.
I will move this question to the XQuery thread, because the XQuery people are listening there.

P.S: Please attach your schema and instance and do not post it.
