This solution will not work but in the simplest cases (no special
markup allowed within the tags).

For additional syntax, a better option would be to define a macro:

  #+MACRO: excl @@html:<span class="org-exclamation">@@$1@@html:</span>@@

Then use it within the buffer:

  A paragraph and {{{excl(some *bold* text within a special
  container)}}}.

This allow for some flexibility. You can even define a babel block and
call it within a paragraph for more complicated (i.e. conditional)
stuff.
