Right, I'll start from the beginning again then.
In a document with a lot of poems laid out as:
<div type="poem">
<head>headers should be included in word index</head>
<lg>
<l>This is a line that really should be included</l>
<l>This is a line that should be included</l>
</lg>
<p>This shouldn't be included</p>
<lg>
<l>This is a line that really should be included</l>
<l>This is a line that should be included</l>
</lg>
</div>

What I want to produce is a word-index of 
poem number and line number, something like:

a (4) -- 1:1, 1:2, 1:3, 1:4, 2:3, 2:5 (well, no poem 2 here ;-) )
be (5) -- 1:head, 1:1, 1:2, 1:3, 1:4
...
really (2) -- 1:1, 1:3, 2:1, 2:3 (if it was in poem 2 as well)

I had previously done word frequency lists as:
-------
<xsl:template match="/">
<xsl:for-each-group select="tokenize(lower-case(string(translate(.,',.!:;',' '))),'\s+')[string(.)]" group-by=".">
 <xsl:sort />[<xsl:value-of select="."/> - <xsl:value-of select="count(current-group())"/>]
 </xsl:for-each-group>
 </xsl:template>
------

And Mike suggested I first build a temporary tree something like:
<xsl:variable name="words">
<xsl:for-each select="tokenize(., '\s+')">
<word value="{.}" position="{position()}"/>
</xsl:for-each>

But I don't see how I a) tokenize only the output of l/text() and
head/text() (it complains of multiple inputs when I do so), and 
b) how I get line-number and poem-number based on position()?
--------------
My completely messed up xsl so far is:
<xsl:template match="l/text()">
<xsl:for-each-group select="$words" group-by=".">
<xsl:sort/>
<xsl:value-of select="word/@value"/> --   
<xsl:for-each select="current-group()">
<a href="#{concat('poem',@poemnumber,'line',@linenumber)}">
<xsl:value-of select="@poemnumber"/>:<xsl:value-of
select="@linenumber"/></a>
</xsl:for-each>
</xsl:for-each-group>
</xsl:template>

<xsl:variable name="words">
<xsl:for-each select="tokenize(lower-case(string(translate(.,',.!:;','
 '))),'\s+')[string(.)]">
<!-- How do I only match text in 'head' and 'l' elements? -->
<xsl:variable name="poemnumber">
<!-- How do I get poem number here?  i.e. xsl:number
     count="div[@type='poem'] when I was matching 'l' " -->
</xsl:variable>
<xsl:variable name="linenumber">
<!-- How do I get line number here? i.e. xsl:number
     from="div[@type='poem'] when I was matching 'l'-->
</xsl:variable>
 <word value="{.}" litposition="{position()}" poemnumber="$poemnumber"
       linenumber="$linenumber"/>
</xsl:for-each>
</xsl:variable>

<!-- some of the things I don't want to match -->
<xsl:template match="teiHeader|foreign|p|milestone|gap" priority="-1" />
------------------

Does that clarify my confuddled state of mind?
