DOCBOOK-APPS: use.id.as.filename may produce invalid filenames

[Gisbert Amm <gia@webde-ag.de>]

Hi,

I use the use.id.as.filename parameter to produce recognizable filenames
from chapter-IDs. Now I've got some problems with German umlauts in
filenames - the hyperlinks do not work in the browser. That's why I've made
the following hack in chunk-common.xsl:

      <!-- filenames, then use the ID to generate the filename. -->
      <xsl:when test="@id and $use.id.as.filename != 0">
-->     <xsl:value-of select="translate(@id, 'äöüÄÖÜß', '_')"/>
        <xsl:value-of select="$html.ext"/>
      </xsl:when>

1) How can I achieve this within my customization layer without copying the
whole template?
2) Wouldn't it be reasonable to provide a parameter to avoid any special
characters in the generated filenames?
