JSON-schema: validating an integer formatted in a string with min and max values

Through a json schema validator (like z-schema), I would like to validate an integer formatted in a string, e.g.:

{
    "myvalue": "45"
}

Currently, the following validation schema is:

{
    "type": "string",
    "pattern": "^[0-9]+$"
}

However, now it would be great to be able to validate a minimum and maximum value, like:

{
    "type": "integer",
    "minimum": 0,
    "maximum": 32
 }

However the above json value "45" is not an integer.

Without changing the type to integer, the best you can do is use the pattern keyword to enforce the range using a regular expression. Here is an example of a regular expression to match integers from 0..32.

/^[1-2]?[0-9]$|^3[0-2]$/
