The following works in both an old Calabash (v 0.9.15) (remove version=) and my
built-from-sources 0.9.19a
<p:declare-step xmlns:p="http://www.w3.org/ns/xproc" version="1.0">
<p:output port="result"/>
<p:identity name="foo">
<p:input port="source">
<p:inline>
<r>
<a>one</a>
<a>two</a>
</r>
</p:inline>
</p:input>
</p:identity>
<p:for-each>
<p:variable name="curr" select="p:iteration-position()"/>
<p:variable name="v2" select="$curr - 1"/>
<p:identity/>
</p:for-each>
</p:declare-step>
Rename v2 to prev and it breaks in my v0.9.19a (but not in 0.9.15),
with the following error:
05-Apr-2010 16:40:43 com.xmlcalabash.util.DefaultXProcMessageListener
error
SEVERE: XD0023:Undeclared variable in XPath expression: $curr
05-Apr-2010 16:40:43 com.xmlcalabash.drivers.Main error
SEVERE: Pipeline failed: err:XD0023: Undeclared variable in XPath
expression: $curr It is a dynamic error if an XPath expression is
encountered which cannot be evaluated (because it is syntactically
incorrect, contains references to unbound variables or unknown
functions, or for any other reason).
How can this be?
