What about the output method? (And XML declaration, for
that matter.) Since you seem to be trying to output text,
perhaps you should give a hint about that to your XSLT
processor - and to other people's XSLT processors?

Why?

I don't believe that's what <xsl:call-template> is for.

And what's that supposed to match?

That's not even well-formed.

And how's that supposed to work?

No, it matches all the <depends> elements in your XML,
because your third template is the only one that actually
does anything. Try removing the first two templates, and
you'll get exactly the same result.

Precisely. You don't match anything. So the template
doesn't do anything.

No, it doesn't. It shows something entirely different. See
above.

For that matter, it's NOT the XSLT output, either. First,
your XSLT is not well-formed, and even if it were
well-formed, there's no sign of B2 anywhere in the XML.
(But that's to be expected; B2's are supposed to be
awfully stealthy, after all.)

If you really want to get help on the newsgroup, I'd
heartily recommend posting your actual code, as well as
actual examples of your input/output. It seems just a bit
disrespectful -- you're asking people for help, but you
can't be bothered to weed out even the most obvious bugs
(such as that </xsl:if>) in your code.

No one's asking you to post your production code or
anything. Just spend a minute or two making sure what
you're posting is relevant to your question. I spent five
minutes of my Sunday morning straightening out your WAG's,
and if I started tinkering with your code in a pretty
cheerful mood, I'm now feeling quite murderous.

That's not how it works. But since you couldn't be bothered
to double-check what you post, I can't be bothered to
explain that in detail to you. Read the spec. Or the
reference. Whatever.

The following works, but you'll just have to figure out why
yourself. It'll do you a world of good, I think.

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet
  version="1.0"
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:output method="text"/>
  <xsl:template match="/features">
    <xsl:apply-templates select="feature"/>
  </xsl:template>
  <xsl:template match="features/feature">
    <xsl:apply-templates
      select="/root/feature[@name=current()/@name]/depends"
      mode="list-dependencies">
      <xsl:with-param name="p-node" select="."/>
    </xsl:apply-templates>
    <xsl:text>&#010;</xsl:text>
  </xsl:template>
  <xsl:template match="depends" mode="list-dependencies">
    <xsl:param name="p-node"/>
    <xsl:text>Feature </xsl:text>
    <xsl:value-of select="$p-node/@name"/>
    <xsl:text> depends on </xsl:text>
    <xsl:value-of select="@name"/>
    <xsl:text>&#010;</xsl:text>
  </xsl:template>
</xsl:stylesheet>
