The tags workspace and tag node type are currently used by the Marketing Tags module. You will have a conflict until we can resolve it in the next major release.

In the next major release (Magnolia CORE 5.6):

• Increment the major version of Marketing Tags.
• Migrate marketing tags out of the tags workspace into a new marketing-tags workspace.
• Create a new content type mgnl:marketing-tag
• Start using the tags workspace for content tags.
• Start using the mgnl:tag content type for content tags
