Description

Description states:

"the valid service name should only contain a-zA-Z0-9_ and can not start with numbers"

It seems to indicate only one service is supported. If multiple services are allowed, it does not indicate how they should be specified i.e. comma-separated or space-separated? If the service name cannot contain spaces, does this imply that space-separated lists are also permitted?
