New NSD check : "count" attribute in DOType.SDO or DOType.DA is only allowed if it is an ARRAY type (isArray="true" in NSD)

[ADehouck]

Some SubDataObjects or Data attributes can be "arrays"

The NSD validation could check that DOType.SDO or DOType.DA have a "count" attribute, only for SDO or DA that are allowed to be arrays, as defined in NSD 61850-7-3:

• SDO is allowed to contain a "count" attribute, only if the corresponding SDO in NSD of 7-3 has CDC / SubDataObject . isArray = "true"
• DA is allowed to contain a "count" attribute, only if the corresponding DA in NSD of 7-3 has CDC / DataAttribute . isArray = "true"

Example of array and "count" attribute in DataTypeTemplate:

This check should be updated,

because "count=0" is equivalent to "count" attribute absent,

The NSD validation could check that DOType.SDO or DOType.DA have a "count" attribute different of zero, only for SDO or DA that are allowed to be arrays, as defined in NSD 61850-7-3
