RE: [xsl] flatten tree

["Michael Kay" <mhk@xxxxxxxxx>]

Write a top-level stylesheet module that imports your "original" stylesheet
module, with the rule:

<xsl:template match="*">
  <xsl:if test="@lang = $selectedLanguage or ((not(@lang) and
$defaultLanguage = $selectedLanguage)">
    <xsl:apply-imports/>
  </xsl:if>
</xsl:template>

This works provided all the elements carrying a lang attribute are processed
using apply-templates rather than for-each, value-of, etc.

Any reason you are using @lang rather than @xml:lang? (I'm just curious. I
always thought the inclusion of @xml:lang in the XML spec, as the only name
that has a predefined meaning, was rather an oddity, and I'm interested that
you are ignoring it and defining your own.)
