<pre>
The tasks's tag.

The tag is less than 500 characters.

SDK compatibility: Although the SDK allows tags to be either
string or
[bytes](https://cloud.google.com/appengine/docs/standard/java/javadoc/com/google/appengine/api/taskqueue/TaskOptions.html#tag-byte:A-),
only UTF-8 encoded tags can be used in Cloud Tasks. If a tag isn't UTF-8
encoded, the tag will be empty when the task is returned by Cloud Tasks.

<code>string tag = 2;</code>

@return The bytes for tag.
