Support of Property Placeholders for Numeric Configuration Parameters with XSD
based configuration
--------------------------------------------------------------------------------------------------
Key: AMQ-2735
URL: https://issues.apache.org/activemq/browse/AMQ-2735
Project: ActiveMQ
Issue Type: Improvement
Reporter: Erich Liebmann
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="[$#](\{.*\}|\(.*\)|\[.*\])"/>
</xs:restriction>
</xs:simpleType>
