Converting uppercase to loswercase using XSLT 1.0 however first character should remain caps

I have an requirement in which I need to convert from uppercase to lowercase. However the first letter should remain uppercase.

Input:<LineStatus>DELETED</LineStatus>

Expected Output: <LineStatus>Deleted</LineStatus>

Below is the code

`<xsl:template match="/">
  <xsl:variable name="smallcase" select="'abcdefghijklmnopqrstuvwxyz'" />
  <xsl:variable name="uppercase" select="'ABCDEFGHIJKLMNOPQRSTUVWXYZ'" />
  <xsl:value-of select="translate(DELETED, $smallcase, $uppercase)" />
</xsl:template>`

This will give the output as deleted

I have tried something like <xsl:value-of select="translate(substring(DELETED,1,1), $smallcase, $uppercase)" /> but it gave me output d

Can anyone please advise?
