XSLT: Add few Variables to List

Question

I am trying to Add a variable to a list from XML using XSTL and create the merged tag but it is not happening.

Source XML.

<Result> 
        <Data>
        <Pass>true</Pass>
        <Data> 
                <account> 
                        <accountNumber>1111</accountNumber> 
                </account> 
                <account> 
                          <accountNumber>2222</accountNumber> 
                </account> 
</Result> 

Requirement is that the output tag should have the list with Pass tag value like below.

<Student>
   <accountNumber>1111</accountNumber> 
   <Pass>true</Pass> 
<Student>  
<Student>
   <accountNumber>2222</accountNumber> 
   <Pass>true</Pass> 
<Student>

Current XSLT file is giving the list but I am unable to add Pass Tag.

<xsl:template match = "Root/Result">
        <xsl:apply-templates select="account"/>
</xsl:template>

<xsl:template match = "account">
  <Student>
    <accountNumber><xsl:value-of select="accountNumber" /></accountNumber>
  </Student> 
</xsl:template>
