Hi there,
whenever I add an element reference to the method generating my schema (see
code below), the system automatically adds the namespace prefix
xmlns:Q1="..." to the schema it generates. How come? (I can get rid of it
when specifying a default namespace, but that's not want I want to...)
Thanks for help,
Dirk

Dirk,
In order to reference anything in any namespace, an xmlns declaration is
required for the namespace. If there isn't one already specified, one is
created on demand. If you have a particular favorite prefix you want to use,
you should set it into the prefix map beforehand, e.g., this will create a null
prefix for the schema's target namespace:
qNameToPrefixMap.put(null, targetNamespace)
