Type definition in XML page with XML Schema

[chobin]

Hi all.
I've a terrible question.
I've to build one XML page (based on a xml schema) that implements a dynamic database. In particular, I would declare something like this:

<?xml version="1.0" encoding="UTF-8"?>
<virtuose xmlns="http://www.virtuose.it/ns/virtuose" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.virtuose.it/ns/virtuose
F:\Tesi\virtuose_1.1.xsd">

<conferenza allowedMessagesTypes="t1" cid="c1" system="true"> <nome>tipimsg</nome> <hook></hook> <messages> <message mid="t1" uid="u1" type="t1"></message> <message mid="t2" uid="u1" type="t1"> <t2:schema> <t2:element name="utente"> <t2:complexType> <t2:sequence> <t2:element name="autenticazione"> <t2:complexType> <t2:sequence> <t2:element name="login" type="string"/> <t2:element name="password" type="string"/> <t2:element name="configurazione" type="stringa"/> </t2:sequence> </t2:complexType> </t2:element> <t2:element name="anagrafica"> <t2:complexType> <t2:sequence> <t2:element name="nome" type="string"/> <t2:element name="cognome" type="string"/> <t2:element name="codfisc" type="string"/> <t2:element name="via" type="string"/> <t2:element name="comune" type="string"/> <t2:element name="provincia" type="string"/> <t2:element name="cap" type="string"/> <t2:element name="telefono" type="string"/> <t2:element name="fax" type="string"/> <t2:element name="cellulare" type="string"/> <t2:element name="email" type="string"/> </t2:sequence> </t2:complexType> </t2:element> <t2:element name="profili"> <t2:attribute name="pids" type="IDREF" use="required"/> </t2:element> </t2:sequence> </t2:complexType> </t2:element> </t2:schema> </message> </messages> </conferenza> <conferenza allowedMessagesTypes="t2" cid="c2" system="true"> <nome>utenti</nome> <hook></hook> <messages> <message mid="u1" uid="u1" type="t2"> <t2:utente> <t2:login>ciccio</t2:login> <t2rofili></t2rofili> </t2:utente> </message> </messages> </conferenza> </virtuose>

So, I've to declare on section <message mid="t2" uid="u1" type="t1"> the type of section

<message mid="u1" uid="u1" type="t2">
<t2:utente>
<t2:login>ciccio</t2:login>
<t2rofili></t2rofili>
</t2:utente>
</message>

but I haven't found in witch way I could include in a XML page a type declaration made with schema.

I hope my message is not too difficult to read...
I'm sorry but I'm an italian student.

Thank you very much
Cheers
