"some thing"= a mail client set up to send HTML mails instead of plain
text, which is something to avoid in the first place.

Most typically, you would encode the data using base64 and put that in
the attribute.  As Daniel says this tends to indicate a very broken design.

So while

<node attr="binary-data-in-base-64"/>

is possible,

<node>
  <attr encoding="base64">binary-data-in-base-64</attr>
  <other-attr>raw-binary-data-with-entities-as-needed</other-attr>
</node>

is a much better design. Attributes are intended for _attributes_, not
data (if a class in your program has 'foo' as a member, then an XML
representation should typically have 'foo' as a sub-element and not an
attribute).
