In-line Hibernate settings for sequence and table id generators, as opposed to a “Map” of config.
E.g.
{noformat}<xsd:complexType name="sequence-generator">
<!- Standard JPA attributes -->
<xsd:attribute name="name" type="xsd:string" use="required"/>
<xsd:attribute name="sequence-name" type="xsd:string"/>
<xsd:attribute name="catalog" type="xsd:string"/>
<xsd:attribute name="schema" type="xsd:string"/>
<xsd:attribute name="initial-value" type="xsd:int"/>
<xsd:attribute name="allocation-size" type="xsd:int"/>
<!-- Extension attributes -->
<xsd:attribute name="per-entity" type="xsd:boolean"/>
<xsd:attribute name="per-entity-suffix" type="xsd:string"/>
<xsd:attribute name="optizer" type="xsd:string"/>
<xsd:attribute name="table-value-column" type="xsd:string"/>
</xsd:complexType name="sequence-generator">{noformat}
And corresponding annotations:
