[wp-docs] Functions that generate html tags?

[Dougal Campbell]

Many of the template functions that we use will return plain text (e.g., 
  the_title, the_author, bloginfo, etc.). But some return HTML-tagged 
content (e.g., wp_list_pages, wp_list_cats, wp_loginout, etc.)

Has anyone documented which functions generate HTML, along with what tag 
structure they use? I did a quick Codex search, but nothing came up. I 
think this would be a very useful reference for theme developers to have.
