Nice set of functions, thanks for sharing.
I ran into a problems with the tag reference page on your site. You can see an example of it by loading the tags file from http://www.scottsh.net/wx/wxtags-error.php
A quick look shows some unexpected behavior from the tags for:
%noaawarningscroll%|
%noaawarningscroll2%|
It seems perhaps they weren’t implemented in your reference page?
