HTML terminology question:TBODY vs P

A TBODY tag can normally hold a number开发者_如何学JAVA of TR tags.

P tag usually holds just textual data.

Is there any special terminology in HTML to differentiate this type of behavior of TBODY? Can I say TBODY is a 'container' type of TAG as opposed to a P tag?

TBODY, THEAD, and TFOOT elements are specifically described as "row groups": http://www.w3.org/TR/html4/struct/tables.html#edef-TBODY

Similarly, DIVs are described as "grouping" elements.

P elements are known as "text" elements.
