XHTML compliance for images

Hi - I've done a through search on this topic, both on the net generally and in these forums, so please forgive me if I'm raising an old question with established answers...

I'd like to know if it's possible these days to get the FCKeditor to produce XHTML strict compliant markup for things like images - or if this kind of support is likely to be built-in in the future?

A common problem for me is the way left and right aligning of images uses the "align" attribute, where style="float:left/right" would be preferable. But I'd also like to deny users the option to set deprecated attributes such as border and padding.

Have others found ways of working around these problems?

background: I regularly churn out Content Management Systems for clients, and have recently decided to switch from TinyMCE to FCKEditor wherever WYSIWYG is needed. I think I would almost recommend WYSIWYG every time if XHTML support was better. And I'm possibly prepared to contribute to a good project (FCKeditor seems the best contender) if better XHTML compliance is something the project team would also like.
