i used this simple schema
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="
http://www.w3.org/2001/XMLSchema"
elementFormDefault="qualified" attributeFormDefault="unqualified">
<xs:element name="Timing">
<xs:complexType>
<xs:choice>
<xs:annotation>
<xs:appinfo>
<jaxb:property name="Content"/>
</xs:appinfo>
</xs:annotation>
<xs:element name="Daily" type="xs:string"/>
<xs:element name="monthly" type="xs:string"/>
<xs:element name="yearly" type="xs:string"/>
<xs:element name="weekly" type="xs:string"/>
</xs:choice>
</xs:complexType>
</xs:element>
</xs:schema>
but I gives a compile error like this
[ERROR] The prefix "jaxb" for element "jaxb:property" is not bound.
