Attribute checked invalid for tag if according to TLD

Question

I'm just curious. Why Tomcat is so strict that it doesn't accept this code in a jspx file:
<label>
     <jsp:element name="input">
          <jsp:attribute name="name">sexo</jsp:attribute>
          <jsp:attribute name="type">radio</jsp:attribute>
          <jsp:attribute name="value">FALSE</jsp:attribute>
          <jsp:attribute name="tabindex">8</jsp:attribute>
          <c:if test="${sexo=='FALSE'}">
               <jsp:attribute name="checked">checked</jsp:attribute>
          </c:if>
     </jsp:element> Femenino
</label>But it does accept this similar one
<label>
     <c:choose>
          <c:when test="${sexo=='FALSE'}">
               <input name="sexo" type="radio" value="FALSE"
                    tabindex="8" checked="chequed"/>
          </c:when>
          <c:otherwise>
               <input name="sexo" type="radio" value="FALSE"
                    tabindex="8"/>
          </c:otherwise>
     </c:choose>
     Femenino
</label>

<label>
     <c:choose>
          <c:when test="${sexo=='FALSE'}">
               <input name="sexo" type="radio" value="FALSE"
                    tabindex="8" checked="chequed"/>
          </c:when>
          <c:otherwise>
               <input name="sexo" type="radio" value="FALSE"
                    tabindex="8"/>
          </c:otherwise>
     </c:choose>

</label>This one is easily to be replaced by<input name="sexo" type="radio" value="false" tabindex="8" ${sexo ? '' : 'checked="checked"'}/>(don't forget to change sexo type from String to Boolean)
