Add node $title_attributes in $content_attributes field title

$title_attributes(node) -> $content_attributes(field). Example rdf attributes(now not exist in field title)

$node.tpl.php

      <?php if ($title): ?>
        <h1<?php print $title_attributes; ?>>
          <a href="<?php print $node_url; ?>" rel="bookmark"><?php print $title; ?></a>
        </h1>
      <?php endif; ?>

field.tpl.php

  <div class="field-items"<?php print $content_attributes; ?>>

Or add attribute in wrapper title
