DeleteByQuery works through an XML call but not JSON to request multiple conditions

Question

Is Solr removing query syntax when passing JSON data and XML data? Solr the docs pretty vague. I am using Solr 5.0.0 for Mac OSX on Java 1.8.

Here are the curl commands in my local field.

curl -v http://localhost:8983/solr/nZ/update -H "Content-Type: application/json" --data-binary

[
{
    "delete": {
        "query":"UserId:5629499534213120 AND SessionId:5066549580791808 AND Kind:event"
    }
}
]

It is output:

{
    "responseHeader": {
        "status": 400,
        "QTime": 2
    },
    "error": {
        "msg": "Document is missing mandatory uniqueKey field: Id",
        "code": 400
    }
}

Running through XML works:

curl -v http://localhost:8983/solr/nZ/update -H "Content-Type: text/xml" --data-binary '
<delete>
<query>UserId:5629499534213120 AND SessionId:5066549580791808 AND Kind:event</query>
</delete>
'

This removes documents and exits:

<?xml version="1.0" encoding="UTF-8"?>
<response>
<lst name="responseHeader"><int name="status">0</int><int name="QTime">57</int></lst>
</response>

I also requested documents that I am trying to delete. There were only 2 of them, and both of them had ID fields. Id is a string and a unique key for the circuit. Is the query syntax for multiple conditions different to JSON than XML?
