Requirements:

The default implementation simply calls aParent.CreateL() to create the entry. 

If creating entries is not supported, implementations should leave with KErrNotSupported. 

Otherwise, implementations should:

1. check aEntry.iType.iUid to ensure that they can create the requested type 

of entry and leave with code KErrNotSupported if they cannot

2. return a CMsvOperation-derived object to provide asynchronous control and 

monitoring of the operation

3. for messages, launch a suitable editor application developed for the message 

type.
