When exporting a VDB with user defined properties, the properties are added to each model in the resulting -vdb.xml. It would make more sense to include them once in the vdb root.

Current -vdb.xml

<?xml version="1.0" encoding="UTF-8" standalone="no"?>

<vdb name="CustomPropertyVdb" version="1">

	<description />

	<property name="validationDateTime" value="Tue Nov 10 13:51:23 CET 2015" />

	<property name="validationVersion" value="8.7.1" />

	<model name="ViewModel2" type="VIRTUAL">

		<property name="lib" value="test" />

		<property name="myCustomProperty" value="someValue" />

		<metadata type="DDL"><![CDATA[ ... ]]></metadata>

	</model>

	<model name="ViewModel" type="VIRTUAL">

		<property name="lib" value="test" />

		<property name="myCustomProperty" value="someValue" />

		<metadata type="DDL"><![CDATA[ ... ]]></metadata>

	</model>

</vdb>

Expected -vdb.xml

<?xml version="1.0" encoding="UTF-8" standalone="no"?>

<vdb name="CustomPropertyVdb" version="1">

	<description />

	<property name="validationDateTime" value="Tue Nov 10 13:51:23 CET 2015" />

	<property name="validationVersion" value="8.7.1" />

	<property name="lib" value="test" />

	<property name="myCustomProperty" value="someValue" />

	<model name="ViewModel2" type="VIRTUAL">

		<metadata type="DDL"><![CDATA[ ... ]]></metadata>

	</model>

	<model name="ViewModel" type="VIRTUAL">

		<metadata type="DDL"><![CDATA[ ... ]]></metadata>

	</model>

</vdb>
