Request to add not opcode in MapTerms in AttributeRegistry

Hi,
As of now MapTerms support AND, OR as shown below


"MapTerms": {
"enum": [
"AND",
"OR"
],
"enumDescriptions": {
"AND": "The operation used for logical 'AND' of dependency terms.",
"OR": "The operation used for logical 'OR' of dependency terms."
},
"type": "string"
},


Is there any plan for adding NOT opcode in MapTerms? If not planned to support, do we have any other workaround or equivalent mapping available to achieve NOT support with existing schema


Thanks,
Mani
