You could rewrite this to
<xsl:variable name="opendocument" select="document('data.xml')/xslt/Open/command" />
As you're only using the string value of the variable above.

Xalan it probably recovering from the parsing error and returning an empty node-set. If it's returning the valua of command even thought data.xml is ill-formed, you probably has the document cached somewhere.
