I see some strange behavior with Xalan-J (as opposed to other
engines, such as XSLTC or Saxon). It happens when an RTF is passed
as a template parameter, and is converted to a node-set (using
exslt:node-set).

<xsl:template match="/">

   <xsl:variable name="t">
     <root>
       <x>1</x>
       <x>2</x>
       <x>3</x>
     </root>
   </xsl:variable>

   <xsl:variable name="tns" select="exslt:node-set($t)/root/x"/>

Should be three element nodes here.

Yes.

select="count($tns)"/></xsl:message>

<xsl:template name="foo">
   <xsl:param name="t"/>
   <xsl:param name="i"/>
   <xsl:variable name="tns" select="exslt:node-set($t)"/>

Second template, declaring its own variable. Should be one element node.

Why? I would think it should be three, and XSLTC/Saxon/xsltproc agree on 
that.

select="count($tns)"/></xsl:message>
   <xsl:message>In template - $tns[2]:<xsl:value-of
select="$tns[2]"/></xsl:message>

   <xsl:if test="$i&lt; count($tns)">

With Xalan-J (2.7.0), this happens only two times; in the first recursion,

   count($tns)

evaluates to 1 instead of 3.

Here's the (stripped) output I'm getting using Xalan 2.7.1:

Type of t: RTF
Type of tns: node-set
Name of tns: x
Nodes in tns: 3
$tns[2]: 2
In template - i: 1
In template - Type of t: node-set
In template - Type of tns: unknown
In template - Name of tns: x
In template - Nodes in tns: 3
In template - $tns[2]: 2
In template - i: 2
In template - Type of t: unknown
In template - Type of tns: unknown
In template - Name of tns: x
In template - Nodes in tns: 1
In template - $tns[2]:

Don't know if this is right or wrong for your test case.

This is consistent with what I see in 2.7.0, and is, as far as I can 
tell, showing a bug.

Should I follow up somewhere else, or raise a bug in JIRA directly?
