RSS <category> tag
Usage
Used with both the <item> and <channel> tags to specify a category for an entire RSS feed or for individual RSS items. The <category> tag makes it possible for RSS feed readers to group websites and content that RSS items are set for in their appropriate categories.
You can use your own category names or predefined categories relative to a domain that contains these predefined categories. If you use a predefined category, make sure to point to it in a hierarchy starting with the top level category and separating each category further down in the hierarchy with a forward slash.
