I would start by using a test within the match="/" template
such as
  <xsl:choose>
    <xsl:when test="AC:validateAcctngCodeResponse/AcctngCodeOut/Status = 'Error'">
which will be true if any of the Status nodes in your structure have
the value 'Error'.  In that case, apply a template matching the first
AcctngCodeOut node whose Status child has the value 'Error':
      <xsl:apply-templates select="(AC:validateAcctngCodeResponse/AcctngCodeOut
             [Status = 'Error'])[1]" />
and in that template, create your output <accountcheckreply> element giving
the failure details.

Otherwise, create a successful <accountcheckreply> element.
