[xsl] Simulate schema-awareness to create comboBoxes

Hello - 

I need some advice, please.  I have a multi-step problem and am not sure the 
best direction to take. I've tried a few different options, but surely someone 
has already solved this more elegantly than what I am doing.... I am attending 
<XML2006> and thought I could wait, but need to come up with something before 
then...

Step 1: I need the global elements in a schema to be represented as options in 
comboBoxes on a JSF page.  

Step 2: I need to compare the user choices (in the instance document) against 
the schema to dynamically add or remove options from the comboBox according to 
the schema cardinality.

I can write a stylesheet to parse the schema to provide the lists, but that 
just gives me a superset and doesn't account for cardinality. And I would still 
have to continue to compare the instance doc against the parsed schema to 
update the comboBoxes as the user makes choices.

I'm using W3C XML Schema, XSLT 2.0, XPath 2.0 and Saxon8.  We have a license 
for SaxonSA, but it either doesn't offer the type of functionality I need or I 
just didn't recognize it.  

Schema:
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema";>

  <xs:element name="root">
    <xs:complexType>
      <xs:sequence>
        <xs:element ref="Item-A" minOccurs="0" maxOccurs="1" />
        <xs:element ref="Item-B" minOccurs="1" maxOccurs="unbounded" />
      </xs:sequence>
    </xs:complexType>
  </xs:element>
            
  <xs:element name="Item-A" type="a-type"/>
  <xs:element name="Item-B" type="b-type"/>
            
  <xs:complexType name="a-type"/>
  <xs:complexType name="b-type"/>
                        
</xs:schema>

Instance 1 > Only option should be 'Item-B':
<?xml version="1.0" encoding="UTF-8"?>
<root>
   <Item-A/>       
</root>

Instance 2 > Options should be 'Item-A' and 'Item-B':
<?xml version="1.0" encoding="UTF-8"?>
<root>
   <Item-B/>       
</root>

If someone could point me in the right direction, I would greatly appreciate it!

Thanks!
