a crash in the name() function of the xslt, when using SQL transformer

           Summary: a crash in the name() function of the xslt, when using
                    SQL transformer
           Product: Cocoon 2
           Version: 2.1m2
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: sitemap components
        AssignedTo: cocoon-dev@xml.apache.org
        ReportedBy: jzarate@havet.es


- when using sqltransformer, if on the pipeline the next transformer is standard 
xslt, you can not use name() or local-name() functions for guessing the names of 
the attributes of SQL namespaced elements. (rowset, by example). it throws al 
ava.lang.indexOutofBounds exception. It only happens when you use it on 
attributes:

<xsl:for-each select="@*">
  <xsl:attribute name="{name()}">blabla</xsl:attribute>
</xsl:for-each>

but <xsl:for-each select="@sql:*">
  <xsl:attrbute name="{name()}">sdfsdf</xsl:attribute>
</xsl:for-each>
works fine.

I think it only happes the firts time you "enter" a sql-namespaced element in 
applying the templates.

In cocoon2.0.4 this used to work fine.

the stacktrace:

java.lang.ArrayIndexOutOfBoundsException: 7 >= 1

the stylesheet:

  <xsl:template match="/">	 	
  <xsl:apply-templates select="block"/>
</xsl:template>

<xsl:template match="block">
  <xsl:copy>
    <xsl:for-each select="@*">
      <xsl:attribute name="{name()}">
        <xsl:value-of select="."/>
      </xsl:attribute>
    </xsl:for-each>
    <xsl:apply-templates select="sql:rowset"/>
  </xsl:copy>
</xsl:template>

<xsl:template match="sql:rowset">
  <xsl:copy>
    <xsl:for-each select="@*">
      <xsl:value-of select="local-name()"/>
    </xsl:for-each>
  </xsl:copy>
</xsl:template>


this stylesheet is applied after a standard SQLTransformation.
and it crashes on "local-name()".
