You should read the tutorial, you should read the taglib docs, and you should 
read the other JSF docs on this tag.  That would illuminate your error.  RTFM.

Nope.  According to
<http://download.oracle.com/javaee/5/javaserverfaces/1.2/docs/tlddocs/h/inputText.html>

there is, too, a "label" attribute for 'h:inputText'.  It is described as a 
"localized user presentable name for this component".  However, it is NOT the 
same as an HTML 'label' tag, nor a JSF 'h:outputLabel' tag.  There's no reason 
to expect to see it in the HTML at all whatsoever, which is why the OP does 
not see it.

The Java EE 6 tutorial at
<http://download.oracle.com/javaee/6/tutorial/doc/bnarf.html#bnarr>
presents the 'h:inputText' tag with a "label" attribute in the very first example:
>>  <h:inputText id="name" label="Customer Name" size="50"
>>     value="#{cashier.name}"
>>     required="true"
>>     requiredMessage="#{customMessages.CustomerName}">
>>     <f:valueChangeListener
>>         type="com.sun.bookstore6.listeners.NameChanged" />
>>  </h:inputText>
>>
>>
>> The label attribute specifies a user-friendly name that will be used in the
>> substitution parameters of error messages displayed for this component.

This description, however, does not match the OP's intended use.  Maybe he 
should read the tutorial and other JSF docs?

For example:
<http://download.oracle.com/docs/cd/E17802_01/j2ee/javaee/javaserverfaces/2.0/docs/pdldocs/facelets/h/inputText.html>
describes the "label" attribute of 'h:inputText' as "A localized user 
presentable name for this component".  There's nothing there to imply anything 
emitted in HTML for it.

Contrast with how the tutorial describes the 'h:outputLabel' tag:
"The h:outputLabel tag is used to attach a label to a specified input field 
for the purpose of making it accessible."

> <h:outputLabel value="First Name" for="fname"/>
> <h:inputText id="fname" value="#{BackingBean.Property}" required="true"/>

This will provide his intended use.  Note that in HTML, "label" is not an 
attribute of the 'input' tag, but a separate tag in its own right.  There is 
no "label" attribute in HTML for the 'input' tag.

So, bottom line:  The 'h:inputText' attribute "label" is not intended to 
generate any HTML, that's why you don't see it.

RTFM.
