Re: grouping sequence question

Hi

I'm doing stylesheet for schema. had stuck by the
sequence grouping for several days
As I checked the grouping methodology on
http://www.dpawson.co.uk/xsl/sect2/N4486.html and 
http://www.jenitennison.com/xslt/grouping/
still not work out my problem by applying those
modules. And I tried to change the bottom
<xsl:apply-templates>
select="xs:element[starts-with(@ref, 'GRP')]"
mode="group"/> to 
<xsl:for-each select ="xs:element |
xs:choice/xs:element | xs:sequence/xs:element |
xs:choice/xs:sequence/*">
        <xsl:apply-templates select="key('at',
generate-id())[generate-id() !=
generate-id(current())]" mode="group"/>
</xsl:for-each>
with a new key: 
<xsl:key name="at" match="xs:element"
use="generate-id((preceding-sibling::xs:element |
self::xs:element | self::xs:sequence/xs:element) )"/>
but output below is not what I desired:
starts
PET starts
MAID starts
ends1 
PET ends
MAID ends
---11
NAME starts
 NAME ends
PHONE starts
 PHONE ends
E-MAIL starts
 E-MAIL ends
MAID starts
 MAID ends

I think the key "at" have some problem or it might
need to add a new template for the key "at", I can't
figure it out. Highly appreciate if anyone can kindly
give any thoughts to me !!

====== schema ======
