Issue
What is that "alternate specification" ?
Does it means that all compliant MSM servers must support a "." AND a "$" as separator ?
Does it means that a NamedVariable has to be used, and if yes, should an address be entered ? (see IEC 9605-1, 14.1.3)
What is the purpose of that alternate specification and why is it mandatory ?

The alternate specification is an mms access specification.
please refer to mms documentation for the definition of the alternate access. |

Triage
The short answer is yes that "$" support is mandatory (see the "shall") in the first part of the paragraph.
A longer answer is that MMS NamedVariables can't contain a ".". Thus when a "."'d name is past into ACSI, it must be translated into a Variable name that is consistent with MMS. Thus the substitution of "$" for ".". There is no need to clarify the text, although I might support an informative note of the following nature: "Informative Note: ISO 9506 NamedVariables do not allow the character "." to be used within the constraints set forth in 61850-8-1. Thus ACSI DataObject Names that contain the "." character must have the "." translated to a character supported within ISO 9506. The chosen character for the translation/substitution is "$"." |
