The spec says:

# If the element's contents are not conformant, it is possible that
# the roundtripping through innerHTML will not work. For instance, if
# the element is a textarea element to which a Comment node has been
# appended, then assigning innerHTML to itself will result in the
# comment being displayed in the text field. Similarly, if, as a
# result of DOM manipulation, the element contains a comment that
# contains the literal string "-->", then when the result of
# serialising the element is parsed, the comment will be truncated at
# that point and the rest of the comment will be interpreted as
# markup. Another example would be making a script element contain a
# text node with the text string "</script>".

It currently says this for innerHTML. Should I say it in other places too? 
Or would something else be better?
