/** The name of the cluster is the name of the tag in the xml configuration.
* Usually it is parsed as an identifier. That is, it can contain underscores, but can not contain hyphens,
* provided that the identifier is not in backquotes.
* But in xml, as a tag name, it's more common to use hyphens.
* This name will be parsed as an expression with an operator minus - not at all what you need.
* Therefore, consider this case separately.
