| Hi,
There is a commentary in the XSD for the unique element saying that either
<column>, <field> or <property> can occur, however there are several cases
we would like to mix these elements. IMO this limitation should not exists.
To illustrate:
Abstract class Person
{
abstract getName();
abstract setName();
String getLastName();
}
<class name="Person">
<discriminator column="disc"/>
<property name="name"/>
<field name="lastName"/>
<unique>
<property name="name"/>
<field name="lastName"/>
<column name="disc"/>
</unique>
</class>
Extract from XSD:
------------------
<xs:element name="unique">
<xs:complexType>
<xs:choice minOccurs="0" maxOccurs="unbounded">
<xs:annotation><xs:documentation>
Please note,
the following subelements must not occur more than once:
- the choice of columns, fields or properties
</xs:documentation></xs:annotation>
