[Q] Possible to select all attributes except some?

Is it possible to write an XPath expression to select all attributes,
except some.

The context is that the new Web interface of the Gmane mail<->NNTP
gateway[1] will use an XSLT style sheet to transform HTML emails to
harmless HTML, by stripping everything in HTML that may be
exploited[2]. 

The style sheet use the following construct to copy elements that
should be preserved:

<xsl:template match="h1|h2|h3|h4|h5|h6|p|a|td">
  <xsl:element name="{name(.)}">
    <xsl:copy-of select="@*"/>
    <xsl:apply-templates/>
  </xsl:element>
</xsl:template>

Is it possible to replace "@*" with an expression that would select
all attributes except the attribute named "background"[3][4]?

Thanx!
