Andrea's memory is correct. And Rudy, my email archive tells me that I
sent you the following explanation on on 15 June 2012. What I think you
really want is a top level type that contains a property type.
============
I also note that your example XML contains Sample1 as a direct child of
Object1. This is not permitted by the GML encoding rules. Sample1 must
be enclosed in a property type like:
<Object1>
<name></name>
<desc></desc>
<sample>
<Sample1>
<name></name>
<desc></desc>
</Sample1>
</sample>
</Object1>
GML contains objects and properties, and no element can be both. Objects
can have properties, but cannot directly contain other objects (without
an intervening property). These rules ensure that properties are names
and type information is encoded explicitly in GML instance documents.
From p20-22 of OGC 07-036 (the GML 3.2.1 specification) see discussion
in 7.1 and in particular:
******
7.1.3 XML Schema definition of GML language
The GML schema consists of W3C XML Schema components that define types
and declare
- XML elements to encode GML objects with identity,
- XML elements to encode GML properties of those objects, and
- XML attributes qualifying those properties.
A GML object is an XML element of a type derived directly or indirectly
from gml:AbstractGMLType. From this
derivation, a GML object shall have a gml:id attribute.
A GML property shall not be derived from gml:AbstractGMLType, shall not
have a gml:id attribute, or any
other attribute of XML type ID.
An element is a GML property if and only if it is a child element of a
GML object.
A GML object shall not appear as the immediate child of a GML object.
Consequently, no element may be both a GML object and a GML property.
