An XSLT (or CSS) stylesheet for general soap would not be terribly useful.
Apart from styling the header and body, the rest would be just serialise the 
source tree in an HTML page. Which is not so easy in XSLT. However, one
thing that would perhaps make your life easier is to transform the 
xlink:hrefs into <a>

  <xsl:template match="@xlink:href">
    <xsl:text> </xsl:text>
    <xsl:value-of select="name()"/>
    <xsl:text>="</xsl:text>
    <a href="{.}"><xsl:value-of select="."/></a>
    <xsl:text>"</xsl:text>
  </xsl:template>

An approximation of what this would give is at

But of course, no PIs in SOAP, and no lower-level mechanism to associate
stylesheets with documents. So take this as a thought experiment.
