$ head -3 manual/source/examples/epics/layout.xml 
<?xml version="1.0" standalone="no" ?>
<hdf5_layout>

cf

$ head -6 manual/source/examples/epics/attributes.xml
<?xml version="1.0" standalone="no" ?>
<!-- Attributes -->
<Attributes

The metadata about XML Schema location is not necessary to validate the XML layout files. The schema location was not added in ADCore since it was mentioned as an addition for layout files.
