[opencms-dev] Configuring or disabling HTML validation in FCKeditor?

[Silvan Ari]

I have just updated from OpenCms version 6.0.4 to version 6.2.3 (running
on WebSphere 5.1). In this version, there seems to be a new
functionality when saving HTML files in WYSIWYG editor: it performs HTML
validation and removes all unrecognized HTML tags. But for my
application, my HTML files contains some custom (not HTML standard)
tags. So question is: How can I configure HTML validation so that it
recognizes my custom tags and does not remove them when saving HTML
file? Or is it possible to disable validation? Are there any other ways
to do it than modify OpenCms source code?
