Re: Result Tree Fragments

See:

http://users.iclway.co.uk/mhkay/saxon/saxon6.0.1/changes.html

and search for:

"In Saxon 5.5, I introduced a change that allows a 
 result-tree-fragment to be implicitly converted to a 
 node-set."

In Saxon 6.0 Michael's "decided to withdraw the facility".

Subject: Result Tree Fragments


| Hello All,
| 
| I have been using Saxon 5.5.1 to help me understand the XSLT spec, but I've
| come to a point where I can't reconcile Saxon's behaviour with the way I
| read the spec. Section 11.1 of the spec describes Result Tree Fragments, and
| in particular, describes how operations permitted on them are a subset of
| those allowed on node-sets.
| 
| Please consider this XSL stylesheet (which can be applied to any xml
| document):
| 
| ------------------------------------------------------------
| 
| <xsl:stylesheet xmlns:xsl='http://www.w3.org/1999/XSL/Transform'
| version="1.0">
| <xsl:output method="text"/>
| 
| <xsl:variable name="a">
|   <NAME>
|     <FIRST>Dave</FIRST>
|     <LAST>Hartnoll</LAST>
|   </NAME>
|   <ADDRESS>
|     <TOWN>Swindon</TOWN>
|     <POSTCODE>SN1 4BA</POSTCODE>
|   </ADDRESS>
| </xsl:variable>
| 
| <xsl:template match="/">
|   Count   : <xsl:value-of select="count($a)"/>
|   Elements: <xsl:value-of select="count($a//*)"/>
|   All text: <xsl:value-of select="$a[1]"/>
|   Town    : <xsl:value-of select="$a/ADDRESS/TOWN"/>
| </xsl:template>
| 
| </xsl:stylesheet>
| 
| ------------------------------------------------------------
| 
| I believe that the spec invalidates all of the xsl:value-of operations,
| although Saxon does give the "right" answers if they were allowed.
| 
| I tried a similar stylesheet with MSXML3 in IE5 and it complained on the
| first value-of that variable a was not a node-set.
| 
| So, my question, is this:
|    a) A bug in Saxon
|    b) A deliberate extension to Saxon
|    c) My misunderstanding of the spec
| 
| Many thanks,
| Dave Hartnoll.
