This actually works due to the fact, that parent deployment unit actually holds "grouped" metadata.
e.g. KernelDeployment for BMDs and ServiceDeployment for SMDs
Hence no BMD or SMD attachment is found in parent dpeloyment unit.

What will make it fail is if we directly put BMD or SMD into deployment unit, which is then the parent of component deployment unit.
Which is what RARDeployer and AppNamingDeployer do.
