Erich Liebmann updated AMQ-2735:
--------------------------------

    Attachment: activemq.xsd

Please find the activemq.xsd schema (from version 5.3.0) with the custom types used instead of xs:boolean, xs:float, xs:long, and xs:integer (to support property placeholders for these types) attached as an example.

> When using the amq namespace to configure an embedded brokers in Spring [1] the ActiveMQ XSD disallows using property placeholders [2] for numeric parameters.
> By introducing the following custom types in the ActiveMQ XSD and using them instead of xs:boolean, xs:float, xs:long, and xs:integer one would be able to use property placeholders for these type of configuration parameters.
>   <xs:simpleType name="placeholderPropertyBooleanValue">
>     <xs:union memberTypes="xs:boolean tns:placeholderPropertyValue"/>
>   </xs:simpleType>
>   
>   <xs:simpleType name="placeholderPropertyFloatValue">
>     <xs:union memberTypes="xs:float tns:placeholderPropertyValue"/>
>   </xs:simpleType>
>   
>   <xs:simpleType name="placeholderPropertyLongValue">
>     <xs:union memberTypes="xs:long tns:placeholderPropertyValue"/>
>   </xs:simpleType>
>   
>   <xs:simpleType name="placeholderPropertyIntegerValue">
>     <xs:union memberTypes="xs:integer tns:placeholderPropertyValue"/>
>   </xs:simpleType>
>   <xs:simpleType name="placeholderPropertyValue">
>     <xs:restriction base="xs:string">
>       <xs:pattern value="[$#](\{.*\}|\(.*\)|\[.*\])"/>
