When I register a template using the layer file, I get a hint suggesting I "Replace with @Template".  There is no @Template annotation, but I see @Template was proposed, but later became @TemplateRegistration.  So I guess that the hint has not be updated when the annotation name changed during development.

Extract from my layer file:
....
<folder name="linsdale">
        <folder name="datamodelcreator">
            <folder name="privatetemplates">
                <file name="database_create" url="builder/database_create.template" >
                    <attr name="template" boolvalue="true" />
                    <attr name="javax.script.ScriptEngine" stringvalue="freemarker"/>
                </file>
.....
