How can I neaten this up?  I've written two templates:

  <xsl:template name="getUnits">
    <xsl:param name="input"/>
    <xsl:value-of select="translate($input, '012345679.', '')"/>
  </xsl:template>

  <xsl:template name="stripUnits">
    <xsl:param name="input"/>
    <xsl:value-of select="translate($input, translate($page-height,
                          '012345679.', ''), '')"/>
  </xsl:template>

This would seem to only _increase_ the verbosity of what I have quoted
above, since now I can't call the templates inside the 'select' of the
variable declaration.  What is the standard idiom here?
