So then what does it mean to say that "variable bindings declared in
templates should be visible to descendants and following siblings"?
This is what it says in the specs.
Actually, it says "for all following-siblings and their descendants".
This means nodes in the stylesheet tree that are following-siblings, or
descendants of following-siblings, of the xsl:variable element in the
stylesheet tree.

Also, the whole reason I wanted to do this was because I am
trying to find
the leftmost daughter of the element ng.
Is there a way to do this? I have really thought about it a
lot but can't
seem to find anything workable.

You've misunderstood the rules. The scope of variables is
static, not
dynamic. It doesn't depend on your source document, and it doesn't
depend on the way in which templates call each other.
You're trying to
reference a variable in one template that's declared in a different
template. What you need to do is pass the value as a parameter from
one template to the other, using xsl:with-param and xsl:param.

so the relevant part of my file looks like this (it's a
subbranch of s):
<ng of='proteins' role='h'>
<nx head='targeting' role='h'>
<W index='92'>the</W>
<W role='h' index='93'>targeting</W>
</nx>
<W index='94'>of</W>
<nx head='proteins' role='k'>
<W index='95'>the</W>
<W index='96'>myosin</W>
<W role='h' index='97'>proteins</W>
</nx>
</ng>
and my stylesheet looks like this:
<xsl:template match="@* | * | comment() |
processing-instruction() |
node()">
<xsl:copy>
<xsl:apply-templates select="@*|node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="s//ng//*[1]" priority="5">
<xsl:variable name="branch">right</xsl:variable>
<xsl:copy>
<xsl:attribute name="branch"><xsl:value-of
select="$branch"/></xsl:attribute>
<xsl:apply-templates select="@*|node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="s//ng//*" priority="4">
<xsl:copy>
<xsl:attribute name="branch"><xsl:value-of
select="$branch"/></xsl:attribute>
<xsl:apply-templates select="@*|node()"/>
</xsl:copy>
</xsl:template>
but when I try to run it, it tells me that the variable
branch has not
been declared, even though it should first have processed
the first
daughter of ng, where it has been declared.
Best,
