Thanks, I think this really boils down, for me, as an misunderstanding/lack of understanding of the documentation.
I'll find another way to do it. Thanks.

AFICT it requires the property values to be queried in a form like "key = value", so a supported XML would have to look something like ... <fields> <field> <fielddata>name=uid</fielddata> <fielddata>type=long</fielddata> </field> ... </fields> ... Then it should be possible to do something like Properties props = config.getProperties("tables.table(0).fields.field(0).fielddata"); for obtaining a properties object with information about the first field of the first table (however I didn't test this). Using getList() allows you to query a single property value at a time only. So you can fetch the names of all fields in a table (as shown in the howtos), but you cannot retrieve a combination of the fields' names and types (or further properties). IIUYC you would like to do something like Properties props = config.getProperties("tables.table.fields.field(0)"); and would obtain a Properties object with the keys "name" and "type" and the values describing the first field, right? I am sorry, but this is not supported ATM. And I am not sure whether it would be possible to implement such a feature in a general and intuitive way: this would require to parse a property's sub properties and somehow combine them?
