The first one will always be used since the path matches first.

## Predefined values

If you have a *path operation* that receives a *path parameter*, but you want the possible valid *path parameter* values to be predefined, you can use a standard Python <abbr title="Enumeration">`Enum`</abbr>.

### Create an `Enum` class

     * then it behaves as "ordinary relocation": the coordinate is preserved from relocated artifact.
     * Finally, if right hand <code>GAV</code> is absent (line looks like <code>GAV&gt;</code>), the left hand matching
     * <code>GAV</code> is banned fully (from resolving).
