RE: XT and SAXON treats //ccc and /descendant::ccc differently

[Bjorn Boxstart <bboxstart@xxxxxxxxxxxxx>]

See the (part of) the X-Path specification below. It tells the differences I think...

Bjorn

// is short for /descendant-or-self::node()/. For example, //para is short for
/descendant-or-self::node()/child::para and so will select any para element in the
document (even a para element that is a document element will be selected by //para since the document
element node is a child of the root node); div//para is short for
div/descendant-or-self::node()/child::para and so will select all para descendants of
div children.
NOTE: The location path //para[1] does not mean the same as the location path
/descendant::para[1]. The latter selects the first descendant para element; the former
selects all descendant para elements that are the first para children of their parents.

Subject:	XT and SAXON treats //ccc and /descendant::ccc differently

I just run to this.

By now I thought that //foo is an abbrev form of /descendant::foo

But running both XT and Saxon I was given the following answer to these:

<xsl:value-of select="//ccc[2]"/>   c12
<xsl:value-of select="//ccc[5]"/>   gives no hit
<xsl:value-of select="/descendant::ccc[5]"/> gives c22  

for following XML file :
<aaa>
<bbb>
<ccc>c11</ccc>
<ccc>c12</ccc>
<ccc>c13</ccc>
</bbb>
<bbb>
<ccc>c21</ccc>
<ccc>c22</ccc>
<ccc>c23</ccc>
</bbb>
</aaa>


Am I missing something or  is there some shared bug ?  Thanks. 

BTW: I am considering to start at Zvon a collection of parser conformity
test files. Is somebody already working on it so I do not reinvent the
wheel?
