Change 

<xsl:value-of select="."/>
<xsl:if test=". = CHOOSE">
  <xsl:attribute name="selected">
  </xsl:attribute>
</xsl:if>

to

<xsl:if test=". = $CHOOSE">
  <xsl:attribute name="selected">selected</xsl:attribute>
</xsl:if>
<xsl:value-of select="."/>

1.  You must specify xsl:attribute immediately after instantiating the
<option> literal result element.  After instantiating the <option>
element, xsl:attributes must be specified before any child nodes are
added to the <option> element or they will have no effect.  So, you need
to move your <option> element contents, namely the value-of until after
the attribute.
2.  Use a $ before CHOOSE to specify that CHOOSE is a variable.
3.  To produce well-formed X(HT)ML, the value of the selected attribute
should be "selected".  The output method processor should reduce this to
just the attribute name (without a value) when outputting html.
