How to prevent certain fields based on another fields value with JSON Schema validator - jsonschema

Question

Depending on the salaryRange the user selects I need to validate differently by requiring some fields and rejecting others. I feel like its a combination of allOf and not but I can't seem to quite get it.
Scenario #1
User selects salaryRange(Hourly)
Require hourlyRate
Prevent the submission of fields feeOne and feeTwo
Scenario #2
User selects salaryRange(0-50k OR 50-100k)
Require feeOne and feeTwo
Prevent the submission of field hourlyRate
Here is my schema
{
"schema": "http://json-schema.org/draft-04/schema#",
"$id": "http://mysite/schemas/job.json#",
"title": "Job",
"description": "Create job",
"type": "object",
"properties": {
"title": { "type": "string" },
"description": { "type": "string" },
"salaryRange": { "enum": ["0-50k", "50-100k", "100-150k", "150-200k", "200-300k", "300k+", "nonExempt", "Hourly"] },
"hourlyRate": {
"type": "number",
"minimum": 0,
"maximum": 300
},
"feeOne": {
"type": "number",
"minimum": 0
},
"feeTwo": {
"type": "number",
"minimum": 0
}
} ,
"additionalProperties": false,
"required": [
"title",
"description",
"salaryRange"
]
}

You can use oneOf and not required to model all possible combinations.
Here is an example in js:

{
"schema": "http://json-schema.org/draft-04/schema#",
"$id": "http://mysite/schemas/job.json#",
"title": "Job",
"description": "Create job",
"type": "object",
"properties": {
"title": { "type": "string" },
"description": { "type": "string" },
"salaryRange": { "enum": ["0-50k", "50-100k", "100-150k", "150-200k", "200-300k", "300k+", "nonExempt", "Hourly"] },
"hourlyRate": {
"type": "number",
"minimum": 0,
"maximum": 300
},
"feeOne": {
"type": "number",
"minimum": 0
},
"feeTwo": {
"type": "number",
"minimum": 0
}
},
"oneOf": [
{
"description": "Disallow fees for hourly salary",
"properties": {
"salaryRange": { "enum": ["Hourly"] }
},
"required": ["hourlyRate"],
"allOf": [
{"not":{"required":["feeOne"]}},
{"not":{"required":["feeTwo"]}}
]
},
{
"description": "Disallow hourly rate for 0-50k, 50-100k salaries",
"properties": {
"salaryRange": { "enum": ["0-50k", "50-100k"] }
},
"required": ["feeOne", "feeTwo"],
"not":{"required":["hourlyRate"]}
},
{
"description": "Allow other cases",
"properties": {
"salaryRange": { "not" : {"enum": ["Hourly", "0-50k", "50-100k"] } }
}
}
],
"additionalProperties": false,
"required": [
"title",
"description",
"salaryRange"
]
}
