class Attribute
from dj_angles.attributes import Attribute
Encapsulates an attribute in an element. Attributes are a key-value pair, but the value can be
`None`.
Examples:
- `<dj-include 'partial.html'>` has 1 attribute: `'partial.html'`. The value is `None`.
- `<dj-include 'partial.html' shadow>` has 2 attributes: `'partial.html'` and `shadow`. The value is `None`.
- `<dj-include 'partial.html' shadow test=True>` has 3 attributes: `'partial.html'`, `shadow`, `test`. The first 2 attributes have a value of `None`, but `test` has a value of `True`.
