Can the combining diacritical marks combine with any base character?

Hi Folks,

Can the combining diacritical marks combine with any base character?

For example, consider this character sequence:

        '>' followed immediately by the
        combining tilde character (U+0303)

Is that legal?

If yes, wouldn't normalizing this:

        <comment>(U+0303)

to NFC result in converting the XML start tag into non-well-formed XML? (It is not well-formed because there is no longer a '>' character after the tag name; rather, there is a '>' character with a tilde on top.)

/Roger
