attribute value test.

I'm trying to test if a nodes parent contains an attribute named 'inserted'
with value 'yes'

<xsl:choose>
     <xsl:when test="../@inserted ='yes' ">
     <xsl:attribute name="style">color: red</xsl:attribute>
      </xsl:when>
     </xsl:choose>


xt keeps telling me there is an unexpected token in the line
beginning xsl:when.


Have tried numerous variants. Stuck.

Can anyone help please.

(email please, I'm on the digest)

TIA DaveP
