Explain that ASCII Seperators are only invalid in XML 1.0, but not in XML 1.1.
+The codepoints used for separating the different parts in the Hash Function Input Algortihm (&sepl1; through &sepl4;) are not allowed in well-formed XML character data. As entities are, per &xmppcore;, required to close a stream if non-well-formed XML data is received, these codepoints cannot occur in the input to the algorithm and their use as separators is safe.
