property Element (Library Schema)

The <property> element specifies a property used by the library. These properties are specific to the library, so there is no predefined set of property names to use. This element is optional and has no child elements.

Syntax

<!-- property -->
<xs:element name="property" minOccurs="0" maxOccurs="unbounded">
    <xs:complexType>
        <xs:complexContent>
            <xs:extension base="xs:anyType">
                <xs:attribute name="name" type="canonical-name" use="required"/>
                    <xs:simpleType name="canonical-name">
                        <xs:restriction base="xs:string">
                            <xs:maxLength value="63"/>
                            <xs:pattern value="[0-9A-Za-z.]*"/>
