Variables are strange in XSLT, in that they don't vary. But XSLT gives
you other ways of doing what you want to do. In your case, you can use
the position() function to get a counter telling you which elem you're
currently on. So you can do:

  <xsl:for-each select="elem">
    <option>
      <xsl:attribute name="value">
        <xsl:value-of select="position()" />
      </xsl:attribute>
      <xsl:value-of select="." />
    </option>
  </xsl:for-each>

Or, more simply using an attribute value template:

  <xsl:for-each select="elem">
    <option value="{position()}">
      <xsl:value-of select="." />
    </option>
  </xsl:for-each>

[I've assumed that the content of the option element should be the
value of the current elem, not the value of the elem element child of
the current elem element.]
  
I hope that helps,
