labelAlign in Vega-Lite 4.0.2 is listed as accepting ConditionalAxisNumber - is this expected?

[DougBurke]

In version 4.0.2 of the Vega-Lite spec I see

        "labelAlign": {
          "anyOf": [
            {
              "$ref": "#/definitions/Align",
              "description": "Horizontal text alignment of axis tick labels, overriding the default setting for the current axis orientation."
            },
            {
              "$ref": "#/definitions/ConditionalAxisNumber"
            }
          ]
        },

I didn't expect the conditional number, but rather something like ConditionalAxisLabelAlign - although this particular definition doesn't exist, I base the name on the labelBaseline rule:

        "labelBaseline": {
          "anyOf": [
            {
              "$ref": "#/definitions/TextBaseline",
              "description": "Vertical text baseline of axis tick labels, overriding the default setting for the current axis orientation. Can be `\"top\"`, `\"middle\"`, `\"bottom\"`, or `\"alphabetic\"`."
            },
            {
              "$ref": "#/definitions/ConditionalAxisLabelBaseline"
            }
          ]
        },

It it is indeed meant to be a number, how do I interpret it? Thanks.

labelAlign?: BaseAxisNoValueRefs['labelAlign'] | ConditionalAxisNumber; looks incorrect.
