+ - ``//categories[@code=1]``
**Limitations**
- Only the last list or container can be queried leaf values. Any ancestor list will have to be referenced by its key name-value pair(s).
- Multiple attributes can only be combined using ``and``. ``or`` and bracketing is not supported.
- Only leaves can be used, leaf-list are not supported.
- Only string and integer values are supported, boolean and float values are not supported.
+ - The key should be supplied with correct data type for it to be queried from DB. In the last example above the attribute code is of type
+ Integer so the cps query will not work if the value is passed as string.
+ eg: ``//categories[@code="1"]`` or ``//categories[@code='1']`` will not work because the key attribute code is treated a string.
**Notes**
- For performance reasons it does not make sense to query using key leaf as attribute. If the key value is known it is better to execute a get request with the complete xpath.
