XSLT Processor - root node template & version question

XSLT Gurus:

Q1: Does it matter (speed wise or best practice) if a template is defined
for the root element? My understanding is that the root node is
automatically processed first by the processor.

Example XML:
<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE RouteCodeMaintLookup SYSTEM "../dtd/routecodemaintlookup.dtd" >
<?xml-stylesheet  type="text/xsl" href="../xsl/routecodemaintlookup.xsl" ?>
<RouteCodeMaintLookup
...   
</RouteCodeMaintLookup>


I'm using the [Sniplet] XSL below versus one that has a
match="RouteCodeMaintLookup" (output is the same I'm just wondering if one
way is better/quicker than the other- they appear to process the same):

<?xml version='1.0'?>
<xsl:stylesheet version="1.1"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>

<xsl:template match="/">
      ...
      
                        <form name="LookUpForm" method="post"
action="{(_at_)servletPath}">
                        <table>
                                <xsl:apply-templates/>
                        </table>
        ...
</xsl:template>

Q2: Since the XSLT 1.1 never made it past WD status is there any gain in
specifying it? I use Xalan-j.

Thanks!
