Committer Notes

This PR removes default-mode="scrubbing to avoid an apply-template loop when the stylesheet is applied to a document.

By setting default-mode="scrubbing" on the xsl:stylesheet element, all templates implicitly have the mode scrubbing.

When applying this stylesheet to a document, the following template matches:

<xsl:template match="/">
  <xsl:param name="source" select="." as="document-node()"/>
  <xsl:document>
    <xsl:apply-templates select="$source" mode="scrubbing"/>
  </xsl:document>
</xsl:template>

The statement <xsl:apply-templates select="$source" mode="scrubbing"/> then causes the same template to match instead of the intended template:

<xsl:template mode="scrubbing" match="* | text() | @*">
  <xsl:copy>
    <xsl:apply-templates mode="#current" select="@*"/>
    <xsl:apply-templates mode="#current"/>
  </xsl:copy>
</xsl:template>

Removing the default-mode="scrubbing restores the correct behavior of the earlier commit.
