<div class="refsect1title">Description</div>
<p> When validating XML parser tries to resolve system entities it
searches in <a href="fn_http_root.html">http_root</a> directory.
If it fails parser iterates internal list of system paths and tries to
find required files there. The function adds new path in this list.
List of system paths contains one directory item by default -
"file://system/".
</p>
<p> NOTE: List of system paths is not persistent. It means that you must
add desired path each time when server starts. An ideal place for this
operation in "autoexec.isql" file. </p>
