The idea is to allow appending a MANIFEST header value as dictated during deployment of a bundle to the already existing header value in the bundle MANIFEST.MF. e.g.

If a bundle 'foo.jar [1.0.0]' has a MANIFEST.MF with following entry -

Import-Package: com.org.bundle.package;version="1.0.0"

and this bundle is deployed using following PLAN entry -

<!-- The intention here is to append the specified package to the existing Import-Package header in the bundle Manifest. -->

<artifact type="bundle" name="foo" version="1.0.0">
<property name="header:Import-Package" value="com.org.anotherbundle.anotherpackage;version=1.0.0"/>
</artifact>

Then, the expansion of 'Import-Package' header during deployment is expected to be 'com.org.bundle.package;version="1.0.0",com.org.anotherbundle.anotherpackage;version="1.0.0"'

To achieve this functionality, the convention for append could be one of the following -
1. If the specified value in the PLAN file is wrapped within append().
2. If the specified value in the PLAN file begins with a '.' or '+' char.

The code to follow for implementing this enhancement (for Virgo) is -

Package: org.eclipse.virgo.kernel.deployer.core.internal
Class: BundleDeploymentPropertiesTransformer.java
Method: doTransformBundleArtifact()
Snippet: manifest.setHeader(headerName, entries.getValue()); // Line 52
