Hello Luis,
I have the impression, that there is a problem in the wording of the textual specification, because it contradicts the XML schema. In the definition of the environment-type there is a choice group, inside which the learning-object appears once, but the group itself has unbounded as maxoccurs attribute:
<xs:choice minOccurs="0" maxOccurs="unbounded">
<xs:element ref="learning-object"/>
<xs:element ref="service"/>
<xs:element ref="environment-ref"/>
</xs:choice>
Thus, the schema clearly allows multiple learning-objects inside an environment. I have the impression that the author of the textual specification only looked at the single occurence of the learning-object element itself and overlooked the multiple occurence of the group where it is contained.
Best regards,
Michael
