Forms: Duplicate ids leads to invalid XHTML 1.0 strict

Hello, I believe the "Recent Poll" block is not valid XHTML 1.0 strict...

These are the errors I get when the block is enabled. Without the block enabled, it validates 1.0 strict.

   1.  Error  Line 263 column 56: ID "poll_view_voting" already defined.

          <form action="/drupal48/node/21"  method="post" id="poll_view_voting">

      An "id" is a unique identifier. Each time this attribute is used in a document it must have a different value. If you are using this attribute as a hook for style sheets it may be more appropriate to use classes (which group elements) than id (which are used to identify exactly one element).
