For accessibility reasons, "label" tags should have an attribute "for" with the id of the input field associated, example :

<label for="ezcoa-183_name">Titre <span class="required">(required)</span>:</label>
<input id="ezcoa-183_name" class="box ezcc-weblog ezcca-weblog_name" size="70" name="ContentObjectAttribute_ezstring_data_text_215486" value="" type="text">

With this code, clicking on the label gives the focus to the input field. This behaviour is also very practical for all users.
