Description of problem:

If you create a label with both the color and weight attributes set 
[setColor() and setFontWeight()]only the color attribute will be 
rendered.  The weight attribute will be dropped.  The problem is in 
label.xsl where 
    <xsl:template match="bebop:label[@color!='' and @weight!='']"
should come after 
   <xsl:template match="bebop:label[@weight!='']"
and
    <xsl:template match="bebop:label[@color!='']"

When the weight and color come before, the color template gets 
matched because it is less specific and comes after the weight and 
weight/color templates.
