ATM the plugins, they are overriding the core (old fashion skins).

AFAIR it was as well about forrest: and xi:.

One workaround can be the following but it leads to the situation of
plugins have to patch core xsl. 

<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:output method="xhtml" version="1.0" encoding="UTF-8"
indent="yes"/>
  <xsl:template match="*[not(contains(name(),'vxml'))]">
    <xsl:call-template name="removeNs"/>
  </xsl:template>
  <xsl:template match="*[contains(name(),'vxml')]">
    <xsl:call-template name="keepNs"/>
  </xsl:template>
  <xsl:template name="keepNs">
    <!-- do not remove element prefix (if any) -->
    <xsl:element name="{name()}"
namespace="http://www.w3.org/2001/vxml">
      <!-- process attributes -->
      <xsl:for-each select="@*">
        <!-- do not remove attribute prefix (if any) -->
        <xsl:attribute name="{name()}">
          <xsl:value-of select="normalize-space(.)"/>
        </xsl:attribute>
      </xsl:for-each>
      <xsl:apply-templates/>
    </xsl:element>
  </xsl:template>
  <xsl:template name="removeNs">
     <!-- remove element prefix (if any) -->
    <xsl:element name="{local-name()}">
      <!-- process attributes -->
      <xsl:for-each select="@*">
        <!-- remove attribute prefix (if any) -->
        <xsl:attribute name="{local-name()}">
          <xsl:value-of select="normalize-space(.)"/>
        </xsl:attribute>
      </xsl:for-each>
      <xsl:apply-templates/>
    </xsl:element>
  </xsl:template>
</xsl:stylesheet>

One could generate an alias:stylesheet (dynamic xsl) that reads in a
configuration file (e.g. {theme}.fv) which defines the to excluded and
included ns. 
<forrest:ns type="include">vxml</forrest:ns>
