Array syntax not powerful enough #6

I'm trying to express tags. So I want to have an array of strings.

The syntax would be something like (playground link):

tags: string[] constrained {
    maxLength: 100,
},

The maxLength now is on tags, but not on the individual items.

"tags": {
  "type": "array",
  "items": {
    "type": "string"
  },
  "maxLength": 100
}

I can't find any syntax in the docs to express it on an individual items level. It also doesn't transform it correctly from Lexicon to MLF.
