Re: test boolean43 seems wrong

[Paul_Dick]

Tom,

I think the point is that the variable created contains just a single root
node with no children and
since a " node-set is true if and only if it is non-empty" TRUE is
returned.   See sections 11.2 XSLT
second bullet,  and Xpath 4.3 (Boolean) second bullet as well.

I've puzzled over conf test boolean43 and can't figure out why
the expected result of "true" is correct. Note the xml doc does not
have a "foo" element. Indeed, Xalan, XT,  and Saxon return
"true" on this test. XSLTC returns "false". We're outnumbered,
but it looks to me like "false" is the correct answer.

Here's the xsl

  <xsl:variable name="emptyResultTreeFragTest">
    <xsl:value-of select="foo"/>
  </xsl:variable>

  <xsl:template match="doc">
    <out>
      <xsl:value-of select="boolean($emptyResultTreeFragTest)"/>
    </out>
  </xsl:template>

I checked the string-length of  the "emptyResultTreeFragTest"
variable and it was 0. I also explicitly converted it to a string
with the string function and printed it out. That showed an
empty string.

So I don't see how applying the boolean function to the variable
can return "true". The XSLT spec says a node-set is true only
if it is non-empty and that a string is true if and only if its
length is non-zero.

What am I missing?
