  50  === 3.1 ===
  51  
  52  * Each plugin must define the tag areas it uses in plugindir/db/tag.php
  53    See https://docs.moodle.org/dev/Tag_API for more details.
  54  * When adding a 'tags' form element the component and itemtype must be specified
  55    in the element attributes.
  56  * Tag name is no longer a unique field in 'tag' table, tags may be separated in
  57    tag collections
  58  * Specifying component is also required when retrieving item tags. This will allow
  59    different components to add tags to the same table (for example blog and forum
  60    posts) and even suggest alternative tagging for the same items.
  61  * All tag_* functions were deprecated because they now require either tag
  62    collection id or component, some were moved to the new class core_tag_tag and
  63    some - to the renderers or templates. As usual, the deprecated function code
  64    and debugging message will provide you with the suggestions of the alternative.
  65    Please note that all deprecated functions will be removed after several major releases.
