why not in p:exec ... ""If cwd is not specified, the cwd is the same as the xproc file one is running."?

Hi,

I'm reading that for p:exec "If cwd is not specified, the current working
directory is implementation-defined."

I'm just wondering why one wouldn't want to have implementations do and the
spec read that ""If cwd is not specified, the current working directory is
the same as the xproc file."

I found that the following did not work until I added a cwd and specified
it be the same dir as the xproc file I'm running

   <p:exec command="java"
cwd="/home/alex/UTSWEBClientWork/hg/automation/xproc/"
name="validate-with-rng"
        result-is-xml="false" wrap-result-lines="true">
        <p:with-option name="args" select="concat('-jar ../jing/jing.jar
-c', ' ',
            $relaxNGSchema , ' ', $xmlFileInput)">
            <p:empty/>
        </p:with-option>
    </p:exec>


Wouldn't you want your cwd to always be the xproc file unless otherwise
specified? Why why not?


So anyway then had to get the directory of the current xproc file I'm
running dynamically

<p:directory-list name="tiger">
        <p:with-option name="path" select="'.'"/>
    </p:directory-list>
    <p:group>
        <p:variable name="cwd" select="/c:directory/@*[namespace-uri()='
http://www.w3.org/XML/1998/namespace' and local-name()='base']"/>

        <p:exec command="java"    name="validate-with-rng"
            result-is-xml="false" wrap-result-lines="true">
            <p:with-option name="args" select="concat('-jar
../jing/jing.jar -c', ' ',
                $relaxNGSchema , ' ', $xmlFileInput)">
                <p:empty/>
            </p:with-option>
            <p:with-option name="cwd"
select="replace($cwd,'file:','')"></p:with-option>
        </p:exec>

    </p:group>

Thanks
