Issues with Label Components with Tapestry 4.0

I have two different "Label" components I'm trying to create.

Issue #1
---------------------------
The first is a simple component (just a Label.jwc and Label.html file in
WEB-INF) that writes a <label>.  I'd like to include the option to write
a "required" indicator.  However, I'm having a difficult time retrieving
a parameter's value.  Here's what I have so far:

Label.jwc
<component-specification allow-informal-parameters="yes">
    <parameter name="key" required="yes"/>
    <parameter name="class" required="no"/>
    <component id="label" type="Any" inherit-informal-parameters="yes"/>
</component-specification>

Label.html
<label jwcid="label"><span jwcid="@Insert"
value="ognl:getMessages().getMessage(key)"/> <div jwcid="@If"
condition="ognl:class == 'required'"><span class="req"> *</span></label>

I'm pretty sure "class" won't work as a parameter name b/c I've seen a
stacktrace using this already.  Regardless, let's pretend it does (I've
tried using other names).  Here's the desired usage:

<label class="required desc" jwcid="@Label" for="phoneNumber"
key="user.phoneNumber">Phone Number</label> produces:

<label class="desc" jwcid="@Label" for="phoneNumber">Phone Number<span
class="req"> *</label>

I'm fine with the result having class="required desc" - I basically just
need some indicator to show a field is required when I'm not wiring up
it's input field as a component.

Issue #2
---------------------------
I'm overriding ValidationDelegate in order to add required field
indicators.  I used to be pre-pending an asterisk to the beginning of
the field, and I had that working.  Now I want to add <span class="req">
to the end of the <label> before the </label> shows up.  I'm using
@FieldLabel and everything *almost* works. I've eliminating error
styling in the class below so it's easier to read.

public class Validator extends ValidationDelegate {
    public void writeLabelSuffix(IFormComponent component,
                                 IMarkupWriter writer, IRequestCycle
cycle) {
        if (component.isRequired()) {
            writer.begin("span");
            writer.attribute("class", "req");
            writer.printRaw(" *");
            writer.end();
        }
    }

The code above results in <label>blah blah</label><span class="req">
*</span>, when I'd rather have the <span> w/in the <label>.  I tried
overriding writeLabelAttributes(), but that doesn't seem to allow me to
create a new tag and write it out w/in the label.  Am I missing
something here?  Has anyone done something like this - or knows how to
add a <span> withing an @FieldLabel?

Thanks,

Matt
