title: Invalid XML comment: invalid character
body: <pre><code>XML comment contains invalid XML: A name was started with an invalid character
  </code></pre>
  
  <p>This is the IntelliSense documentation message I get. Something is obviously wrong with my documentation but I can't find what.</p>

      /// The local-part of an email adress may use any of these ASCII characters (As according to RFC 5322 &lt;see href="http://tools.ietf.org/html/rfc5322"&gt;&lt;/see&gt;):
      /// - Uppercase and lowercase English letters (a–z, A–Z) (ASCII: 65-90, 97-122)
      /// - Digits 0 to 9 (ASCII: 48-57)
      /// - Characters !#$%&amp;'*+-/=?^_`{|}~ (ASCII: 33, 35-39, 42, 43, 45, 47, 61, 63, 94-96, 123-126)
      /// - Character . (dot, period, full stop) (ASCII: 46) provided that it is not the first or last character, and provided also that it does not appear two or more times consecutively (e.g. John..Doe@example.com is not allowed.)
      /// - Special characters are allowed with restrictions. They are: Space and "(),:;&lt;&gt;@[\] (ASCII: 32, 34, 40, 41, 44, 58, 59, 60, 62, 64, 91-93)
      /// - The restrictions for special characters are that they must only be used when contained between quotation marks, and that 3 of them (The space, backslash \ and quotation mark " (ASCII: 32, 92, 34)) must also be preceded by a backslash \ (e.g. "\ \\\"").
      /// &lt;/summary&gt;

  <p>My guess is that it has something to do with all the characters, but I dunno really...</p>
