That's not a problem. You would need to generate the containing
<xsd:schema> element yourself and then add type/element nodes to it.
Once you have that piece in place, the prefix declaration will show up
on the <xsd:schema> element. The prefix declaration has to appear
somewhere.

Thanks again.
1. Yes.
2. Cool. That was really helpful. I was able to manipulate at DOM nodes
level to experiment generating my common.xsd. I still need to learn
cursor API. But I have a follow up question. My original XSD and
generated XSD files have slightly different structure. Are there any
options to save the generated XSD in the original format?
ORIGINAL XSD (just a snippet from the original)
<?xml version="1.0" encoding="utf-8"?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<xsd:complexType name="configClassesType">
<xsd:sequence>
<xsd:choice minOccurs="0" maxOccurs="unbounded">
<xsd:element name="Cluster" type="ClusterType" />
<xsd:element name="LocalBox" type="LocalBoxType" />
<xsd:element name="Services" type="ServicesType" />
</xsd:choice>
</xsd:sequence>
</xsd:complexType>
And GENERATED one (again the corresponding snippet)
<?xml version="1.0" encoding="UTF-8"?>
<xsd:complexType name="configClassesType"
xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<xsd:sequence>
<xsd:choice minOccurs="0" maxOccurs="unbounded">
<xsd:element name="Cluster" type="ClusterType"/>
<xsd:element name="LocalBox" type="LocalBoxType"/>
<xsd:element name="Services" type="ServicesType"/>
</xsd:choice>
</xsd:sequence>
</xsd:complexType><?xml version="1.0" encoding="UTF-8"?>
Difference: difference is that the enclosing element '<xsd:schema
xmlns:xsd="http://www.w3.org/2001/XMLSchema">' is gone from the
generated one and instead it gets added to each global type element as
an attribute.

Answers:
1. There is nothing special about simple types, so you would need to
decide the criteria to use (like facets and derivation). I would point
out however that minOccurs and maxOccurs are applicable for Schema
Properties in general, regardless if they are elements or not and
regardless of the their type (if they are elements).
2. Yeah, that is the basic answer. But, since you've asked, there is one
small thing that I usually don't recommend, but in your case I'm making
an exception because it could prove immensely useful: ((SchemaTypeImpl)
schemaType).getParseObject(). This is NOT guaranteed to be non-null
(depending on how you built your Schemas) but if it is non-null, it will
contain the XML representation (as an XmlObject) of the Schema type in
question (there is a similar method for SchemaGlobalElementImpl)
Good luck with your project,
Radu
