[xsl] Mulberry processor-version.xsl

There is a unusual stylesheet at Mulberry that I would like to ask
some questions about:

  http://www.mulberrytech.com/xsl/xsl-list/processor-version.xsl

Q1) There is no template but I recall reading somewhere where
    the entirety of the file can be a template body sans an
    explicit <xsl:template> wrapper. Could someone clarify?

Q2) What does this code accomplish? Doesn't the test always fail?

    <xsl:when test="false()">
     <msxsl:if test=".">
      <p>Vendor: Microsoft
      <br/>Processor version:
       Original IE5 (or old version of other processor)</p>
     </msxsl:if>
    </xsl:when>

In reference to the following:

    <msxsl:choose>
     <msxsl:when test=".">
     </msxsl:when>
     <msxsl:otherwise>
       <p>Vendor: <xsl:value-of select="system-property('xsl:vendor')"/>
       <br/>Vendor URL:
        <xsl:value-of select="system-property('xsl:vendor-url')"/></p>
     </msxsl:otherwise>
    </msxsl:choose>

Q3) What is <msxsl:when test="."> testing? What is the current
node?

Q4) Why are xsl:* statements embedded within msxsl:* statements?
