Subject: [xsl] grouping like items into one

I know I have done this with xsl 1.0 before and could figure 
it out, but 1.0 is painful :) So I am trying to figure it out 
with 2.0 and am getting stuck. I am running into that "how do 
I know what to look up if I don't know how to spell it" jam.
I looked at the xsl:for-each-group element, but I don't think 
that will work in this situation.
Someone want to take a whack at it?


I want to group bordered text into one border <span>, but 
leave italic text ( and other styles ) in individual nodes.

_______Source XML__________________
<?xml version="1.0" encoding="UTF-8" standalone="yes"?> <DD> 
<text italic="false" border="">a </text> <text italic="false" 
border="single">b </text> <text italic="true" 
border="single">c </text> <text italic="true" border="">d 
</text> <text italic="false" border="">e </text> <text 
italic="false" border="single">f </text> <text italic="false" 
border="single">g </text> <text italic="false" border="">h 
</text> <text italic="true" border="single">i </text> <text 
italic="true" border="">j </text> </DD>

_____Current output (formated for 
readability)________________ a <span class="border">b </span> 
<span class="border"><i>c </i></span> <i>d </i> e <span 
class="border">f </span> <span class="border">g </span> h 
<span class="border"><i>i </i></span> <i>j </i>


____ Desired output (formated for readability) ______________
____ Note how there is one <span....> around b <i>c </> and   
around "f 
g " ___
a
<span class="border">b <i>c </i></span>
<i>d </i>
e
<span class="border">f g </span>
