# Are machine tag namespaces reserved?
No. Anyone can use a namespace for anything they want.
If you are concerned about colliding namespaces you should consider
adding an additional machine tag to define your namespace. For example :
dc:subject=tags
xmlns:dc=http://purl.org/dc/elements/1.1/
Like tags, in general, we expect (hope?) that the community will
develop its own standards by consensus over time.
