The tag access has no description and I've seen it used in at least three different contexts:
- Microsoft Access, but there's already a tag ms-access for this.
- privileges a user has on an object, but there's already a tag access-control which can be used in some cases for this, or just use privileges.
- index access paths, where I think the tag is extraneous. indexing or similar should be enough.
If it was up to me, I would remove this tag and blacklist it.
