Re: [xsl] Multiple/conditional import problem

Thanks Dave!

The properties will be usually grouped into some classes - and then
one stylesheet per class.

I think for now I'll just import those specific stylesheets I've
developed myself into default.xsl, ant figure out the pre-processing
step later.

Usually specific stylesheet (image.xsl) imports general one
(default.xsl), however in this case it would be the way around - but
it makes sense here?

Can you take a look at the pseudo-code below just to make sure I got it
right:

default.xsl:

<xsl:imports href="image.xsl"/>

<xsl:template match="property">
  <dt>
    <xsl:value-of select="@name"/>
  </dt>
  <dd>
    <xsl:apply-templates select="value"/>
    <xsl:apply-imports/>
  </dd>
<xsl:template>

<xsl:template match="property/value">
  <xsl:value-of select="."/>
</xsltemplate>

image.xsl:

<xsl:template match="property[@name = 'image']/value">
  <img src="{.}"/>
<xsl:template>

Do I need <xsl:apply-templates select="value"/> in default.xsl or will
it be called automatically if <xsl:apply-imports/> fails to find match
in image.xsl?
