Using vCloud Suite SDK for tag management on vsphere 5.5 or earlier

Hello,

I researched alot about this topic and found out that  5.5 and earlier versions of vSphere have tagging capability but they do not provide public API for tag management so we won’t be able to access those tags using  SDK versions  5.5 and earlier. But now since vCloud suite SDK provides this capability, can we use this SDK to target it for vcenter 5.5 and earlier? I know PowerCLI is another option, but I do not want to use automation SDK and want to stick to Java management SDK.
