| <p>CQL distinguishes between <em>reserved</em> and <em>non-reserved</em> keywords. |
| Reserved keywords cannot be used as identifier, they are truly reserved |
| for the language (but one can enclose a reserved keyword by |
| double-quotes to use it as an identifier). Non-reserved keywords however |
| only have a specific meaning in certain context but can used as |
| identifier otherwise. The only <em>raison d’être</em> of these non-reserved |
| keywords is convenience: some keyword are non-reserved when it was |
| always easy for the parser to decide whether they were used as keywords |
| or not.</p> |
