The key of the key-value pair is a simple keyword string. Other parameters

that describe the key-value pair is specified in Fragment.KeyValue:

1. grammar - pyparsing grammar to parse the value of key-value pair

2. min - the minimum number of value in the key entry, None means no minimum

3. max - the maximum number of value in the key entry, None means no maximum

4. required - if the key-value pair is required in the fragment

Setting min=max=1 means that the key has a single value.
