When exporting XML as fmxmlresult.xml when does FilMaker populate the content of the layout attribute?

When exporting XML as fmxmlresult.xml when does FileMaker populate the content of the layout attribute?

Usually it looks like

<DATABASE DATEFORMAT="D/m/yyyy" LAYOUT="" NAME="Menu.fp7" RECORDS="51" TIMEFORMAT="k:mm:ss "/>

Yet sometimes it looks like this

<DATABASE DATEFORMAT="D/m/yyyy" LAYOUT="menu" NAME="Menu.fp7" RECORDS="51" TIMEFORMAT="k:mm:ss "/>

Then again when querying the XML RPC it always look like this

<datasource database="Menu.fp7" date-format="MM/dd/yyyy" layout="menu" table="Menu" time-format="HH:mm:ss" timestamp-format="MM/dd/yyyy HH:mm:ss" total-count="0" />

Asking the question myself, answering the question myself as well. Checking the following checkbox populates the LAYOUT-attribute of FMPXMLRESULT
