The CuteEditor converts attributes in all lower case (which is XHTML compliant) to upper case (second word) when saved.  Such as:

 

<table style="BORDER-RIGHT: 0px; PADDING-RIGHT: 0px; BORDER-TOP: 0px; PADDING-LEFT: 0px; PADDING-BOTTOM: 0px; MARGIN: 0px; BORDER-LEFT: 0px; WIDTH: 100%; PADDING-TOP: 0px; BORDER-BOTTOM: 0px" cellSpacing=0 cellPadding=0>

 

The cellspacing and cellpadding attributes are converted to cellSpacing and cellPadding instead of leaving them all lower case.  The causes the W3C validation to throw errors, because the inclusion of an upper-case character is not valid. 

 

Please advise.
