What is the syntax 
to link multiple child style sheets into
a master style sheet 
...
 
e.g. 
header style 
sheet     header.xsl
footer style 
sheet      footer.xsl
data style 
sheet       data001.xsl
master style 
sheet.  master.xsl
 
this way i can 
always reference the master.xsl
style sheet from 
any/all   *.xml files
and then link in 
header.xsl (this one never changes)
then the appropriate 
data.xsl (this one changes)
then link the 
footer.xsl (this one never changes)
 
this way if I make 
any changes to the header
or the footer, they 
are edited in just one file
and reflected in all 
master.xsl files
 
 
<?xml 
version='1.0'?>
<xsl:stylesheet 
xmlns:xsl="http://www.w3.org>
<xsl:template 
match="/">
 
<!-- include the 
header.xsl file here -->
<!-- how to 
include syntax here -->
 
<!-- include the 
data.xsl file here -->
<!-- how to 
include syntax here -->
 
 
<!-- include the 
footer.xsl file here -->
<!-- how to 
include syntax here -->
 
 
 
</xsl:template>
</xsl:stylesheet>
 
also
what is the proper 
syntax in the included external xsl files
 
are they structured 
the same as the master.xsl file would
e.g.
<?xml 
version='1.0'?>
<xsl:stylesheet 
xmlns:xsl="http://www.w3.org>
<xsl:template 
match="/">
 
<!-- this is the 
header xsl file -->
 
</xsl:template>
</xsl:stylesheet>
