- autolink (optional)
If unspecified, any plaintext links in the comment body will be automatically linked if the blog is configured to do that on the comment preferences screen. If this attribute is specified, it will override the blog preference.
- convert_breaks (optional)
By default, the comment text is formatted according to the comment text formatting choice in the blog preferences. If convert_breaks is disabled, the raw content of the comment body is output without any re-formatting applied.
- words (optional)
Limits the length of the comment body to the specified number of words. This is useful for producing a list of recent comments with an excerpt of each. When this attribute is specified, autolink and convert_breaks attributes are ignored.
