Separating layout and content

Hi,

i have several types of documents that i want to display in HTML having
the same overall layout. Doctype specific differences are kept in a
doctype specific stylesheet.

At the moment the following solution works:

1. The doctype specific stylesheet doctypeA.xsl calls
	<xsl:call-template name="doLayout"/>

2. doLayout is imported from layout.xsl and looks as follows:

<xsl:template name="doLayout">
	<!-- e.g. a rather simple snipet of site layout -->
	<table width="100%" cellpadding="3" class="TableRahmenkpl">
		<tr valign="top">
			<td class="TD">
				<xsl:call-template name="navigation" />
				<xsl:call-template name="head" />
				<xsl:call-template name="title" />
				<xsl:call-template name="text" />
			</td>
		</tr>
	</table>
</xsl:template>

3. Each of the doctype specifiy stylesheets holds the above templates
implementing each part of the doctype specific output:
<xsl:template name="navigation">
	<!-- output the doctype specific navigation -->
	...
</xsl:template>
<xsl:template name="head">
	<!-- output the doctype specific head -->
	...
</xsl:template>
<xsl:template name="title">
	<!-- output the doctype specific title -->
	...
</xsl:template>
<xsl:template name="text">
	<!-- output the doctype specific text -->
	...
</xsl:template>

I wonder whether there is a better way to do this. Any Ideas?

Best regards,
Thomas.
