name of attributes like name() function for elements?

Hi all,

Is it possible to get the name of an attribute in the same way, as
with the name() function for elements?

Problem:

When merging to files - in my case RelaxNG with some proprietary
extensions residing in a seperate file - I use a key function to
retrieve the content of an element node of the extension file:

<xsl:key name="insert.template.elem" match="*" use="name()"/>

and applying it this way:

<xsl:template match="@* |node()" mode="copy.rng" >
<xsl:choose>
  <xsl:when test="name()='element' ">
    <xsl:element name="{name()}">
      <xsl:variable name="elem.name" select="@name"/>
      <xsl:attribute name="name"><xsl:value-of select="$elem.name"/>
      </xsl:attribute>
      <sm:map>
        <sm:item table="kennungen">
          <xsl:attribute name="field">
            <xsl:for-each select="$insertTemplate"><xsl:value-of 
select="key('insert.template.elem',$elem.name)"/></xsl:for-each>
          </xsl:attribute>
        </sm:item>
      </sm:map>
      <xsl:apply-templates mode="copy.rng"/>
    </xsl:element>
  </xsl:when>
...

But there is also information stored in attributes I need to retrieve
in a similar way. How can this be accomplished? I'm imagining
something like the following:

<xsl:key name="insert.template.attr" match="@*" use="attr-name()"/>
                                           ^^^^      ^^^^
                                       something like this!
and then applying it again this way:

...
  <xsl:when test="name()='attribute' ">
    <xsl:element name="{name()}">
      <xsl:variable name="attr.name" select="@name"/>
      <xsl:attribute name="name"><xsl:value-of select="$attr.name"/>
      </xsl:attribute>
      <sm:map>
        <sm:item table="kennungen">
          <xsl:attribute name="field">
            <xsl:for-each select="$insertTemplate"><xsl:value-of 
select="key('insert.template.attr',$attr.name)"/></xsl:for-each>
          </xsl:attribute>
        </sm:item>
      </sm:map>
      <xsl:apply-templates mode="copy.rng"/>
    </xsl:element>
  </xsl:when>
...


Thanks in advance,
Georges
