This filter converts a XHTML-compatible shorttag <input ... /> to a HTML4-compatible tag <input ...>.

Example:

{% for field in form %} <dt>{{ field.label_tag }}</dt> <dd> {{ field.errors }} {{ field|remove_shorttag }} </dd> {% endfor %}

This will produce html4-compatible output, opposed to newform's normal XHTML output.
