I think DocBook does not have presentational markup. Not more than XHTML does. There are tags <code><emphasis></code> and <code><emphasis role="strong"></code>, but that's just as much as <code><em></code> and <code><strong></code> in XHTML. [[User:62.176.30.2|62.176.30.2]] 19:02, 26 Apr 2005 (UTC)
== *roff as a markup language ==
What about '''roff''', '''troff''', '''nroff''', '''groff''', etc.? Where do they fit in in this scheme?
:Agree, they should also be mentioned. [[User:Egil|Egil]] 10:09, 29 December 2006 (UTC)
== [[OpenDocument]] ==
Shouldn’t OpenDocument be included here? —[[User:Masatran|Masatran]] 18:06, 16 October 2005 (UTC)
OpenDocument is XML-based, but it's not a markup language in the same way these others (including *roff) are; it's not designed to be written by hand in a text editor, but to be the file format for a WYSIWYG word processor. Most would agree that it's a file format more than a markup language of its own.
