Use the identity transformation (a simple template found in the XSLT 1.0 spec
under "Copying") to make the default be to recursively copy all nodes from the
source tree to the result tree.

<xsl:template match="@*|node()">
  <xsl:copy>
    <xsl:apply-templates select="@*|node()"/>
  </xsl:copy>
</xsl:template>

Add one template that matches the element that needs the new attribute. This
template should do the same recursive copy of its children, but only after
adding the new attribute:

<xsl:template match="foo">
  <xsl:copy>
    <xsl:attribute name="newAttr">newValue</xsl:attribute>
    <xsl:apply-templates select="@*|node()"/>
  </xsl:copy>
</xsl:template>

It will match at a higher priority than the other template, so you don't
have to worry about conflicts.

Saving the XSLT processor's output is a matter for the process that invoked
the XSLT processor.
