Defines tags for use in image search and image generation. The second letter of the definition defines the tag type: suggested (t=, ts=), required (tr=) or avoid (ta=). Used in Image Search.
A required tag "type=x" is usually added to FileData automatically. "x" in this case is the FileData type, for example: "type=character", "type=interaction". This can be manually overridden by adding a "type=x" tag in the file.
If not defined: The only tag is "type=x". Image Search will result in a mostly random images.
Example: "tr=type=character"
