DOCBOOK-APPS: XSL stylesheets admon.graphic template using wrongextension?

[pilgrim_mark at yahoo dot com]

In DocBook XSL stylesheets 1.24, html/admon.xsl,
<xsl:template name="admon.graphic">, I see names for
graphics files: note.gif, warning.gif, etc.  However,
in the images/ directory of the stylesheet
distribution, I only see PNG files named note.png,
warning.png, etc.  I put the following hack in my
custom stylesheet to use the .png filenames instead
(nothing is changed except the filenames).  Is this an
acceptable solution, and if so, can it be integrated
into the main stylesheets?

<xsl:template name="admon.graphic">
  <xsl:param name="node" select="."/>
  <xsl:value-of select="$admon.graphics.path"/>
  <xsl:choose>
    <xsl:when
test="name($node)='note'">note.png</xsl:when>
    <xsl:when
test="name($node)='warning'">warning.png</xsl:when>
    <xsl:when
test="name($node)='caution'">caution.png</xsl:when>
    <xsl:when
test="name($node)='tip'">tip.png</xsl:when>
    <xsl:when
test="name($node)='important'">important.png</xsl:when>
    <xsl:otherwise>note.png</xsl:otherwise>
  </xsl:choose>
</xsl:template>
