Re: Catching an XD0029

Well, the p:data can't stand by itself. However if I put it in a p:variable,
it's actually caught:


<?xml version="1.0" encoding="UTF-8"?>
<p:declare-step xmlns:p="http://www.w3.org/ns/xproc"
    xmlns:c="http://www.w3.org/ns/xproc-step" version="1.0">
    <p:input port="source"/>
    <p:output port="result"/>

    <p:try>
        <p:group>
            <p:variable name="foo" select=".">
                <p:data href="doesNotExist"/>
            </p:variable>
            <p:identity>
                <p:input port="source">
                    <p:inline>
                        <ok/>
                    </p:inline>
                </p:input>
            </p:identity>
        </p:group>
        <p:catch>
            <p:identity>
                <p:input port="source">
                    <p:inline>
                        <error/>
                    </p:inline>
                </p:input>
            </p:identity>
        </p:catch>
    </p:try>

</p:declare-step>
