Proprietary tags - invalid HTML

Question

Does anyone know why RoboHelp adds <spaces> tags and what are they used for? Is there a way to prevent RoboHelp from adding it? Since they're not valid HTML tags, the topics created using RoboHelp really aren't compliant. Also, I've never seen the CSS attribute "x-right" and "x-cell" either. Unfortunately Google doesn't have any useful information on these tags.
Any information would be helpful.
Thanks!

Hi,
These attributes and tags are just RoboHelps way of maintaining files, and don't appear in the output.
If I recall correctly, RoboHelp inserts the spaces tag whenever you add a couple of spaces in the WYSIWYG editor. If you don't want that, insert some non-breakable spaces (& nbsp;) in html mode. (without the space though, but if I add the html character, the forum turns it into a non-breakable space :-( )
The attributes x-right, x-cell, x-save-position, x-use-null-cells, x-next-tag, and so on help RoboHelp position elements and control how RoboHelp maintains them. Example:
H1 {
x-next-class: Body-Text;
x-next-type: P;
in the definition of a style, makes that the next paragraph after a header is a standard paragraph with the class Body-Text. You can remove these from your style sheet, but RoboHelp may put them back whenever you edit the css trough the built-in css editor.
I wouldn't worry about the x- commands in topics, as there removed when you generate your output, and RoboHelp just adds them again when you remove them in html mode. The only way to get rid of them is to edit the html files in an external editor.
