22195	Use constants to define built-in tags	Russell Keith-Magee	Tomáš Ehrlich	"Via discussion on [https://groups.google.com/forum/#!msg/django-developers/GeAWvy_V0sQ/09DFkcNTJ3wJ django-developers]:

The code for system checks currently uses freeform strings to register against tags (e.g., `@register('compatibility')`). 

This is potentially prone to error, since you can easily mistype the string, and then the check won't get caught by the tag.

Internally, we should be using constants for built-in tags."	Cleanup/optimization	closed	Core (System checks)	1.7-alpha-1	Normal	fixed		Tim Martin tomas.ehrlich@…	Accepted	1	0	0	0	1	0
