Okay, I don't understand your sentence, and I'm afraid you didn't understood
mine. So I will recap for my last mail on that topic:
if (a & b) is in the script and CDATA is not used this will be a fatal error
if (a < b) is in the script and CDATA is not used this will be a fatal error
=> this is not XML this can't be parsed.
if enclosed in CDATA this can be parsed as-is
if not enclosed in CDATA this would have to be saved as
(a & b)
or
(a < b)
which makes the script language simply very hard to read and prone to break.
That's why libxml2 when saving a script or style element from and XHTML
document do enclose the content in CDATA, the change in recent version is
that it does this only if & or < is found in the content of the script or
style element.
