1.8.2 Publisher Names
Each publisher has a name that is a [UNICODE] string. This name MUST be unique across all publishers on the same server. Publisher names MUST be treated in a case-insensitive manner, MUST be limited to 255 characters, and MUST NOT begin with the backslash \. The set of publisher names also includes all event sources (for more information, see [MSDN-EVENTS]). Apart from these restrictions, there are no character restrictions on publisher names. However, publisher names SHOULD<2> be prefixed with a unique value (such as the name of the entity that created the publisher) so that the publishers are easily identifiable and readable.
