Interesting inconsistency in form tag with options and option

[testing123]

There are basically three ways to do a dropdown. If the myoptions[i].value is a space (ie I want the option in the dropdown to display as blank) the following results happen:

Case 1:

<c:forEach items="${myoptions}" var="currOption" varStatus="status">
	<form:option value="${currOption.key}">${currOption.value}</form:option>
</c:forEach>

result:

<select>
	<option value="ID1">ID1</option>
	<option value="ID2">ID2</option>
</select>

Case 2:

<c:forEach items="${myoptions}" var="currOption" varStatus="status">
	<form:option value="${currOption.key}" label="${currOption.value}" />
</c:forEach>

result:

<select>
	<option value="ID1"> </option>
	<option value="ID2"> </option>
</select>

Case 3:

<form:options items="${myoptions}" itemValue="key" itemLabel="value" />

result:

<select>
	<option value="ID1"> </option>
	<option value="ID2"> </option>
</select>

Because I can just add the label attribute and have it work the way I want it is no big deal. I was just wondering if anyone had some comments on why it works this way.
