web-manifest.json icons purpose

[5im0n]

The W3C documentation specify that the purpose attribute of an icon should be:

an unordered set of unique space-separated tokens that are ASCII case-insensitive

https://www.w3.org/TR/appmanifest/#purpose-member

Currently the JSON schema is :

"purpose": {
  "type": "string",
  "enum": [ "badge", "maskable", "any" ],
  "default": "any"
},

which don't allow value like "purpose": "maskable any"

@aotd1 Is there a way to specify this kind of rule in the schema ?
