Consumer unable to parse EdmType if it's a collection of complex types

[GoogleCodeExporter]

What steps will reproduce the problem?
1. create an OData service that will have a collection of complex types as 
property
2. execute getMetadata() via consumer class

What is the expected output? What do you see instead?
Exception has been thrown. Here is a stack trace.

Tony, mind taking a look at this?

sure...(several  minutes later):  the attached metadata is not valid CSDL. Line 
5 is incorrect syntax for specifying a collection:

It shows: <Property Name="Row" Nullable="false" 
Type="Collection(tns.MultiStringRow)" />

The correct way is:
<Property Name="Row" Nullable="false" Type="tns.MultiStringRow" 
CollectionKind="None|Bag|List" />

Is this metadata from a real service?  How is the producer implemented?  Is 
this one of those "we need to be lenient in our implementation" type scenarios?

I am also facing a similar issue. My service exposes as CSDL 2.0. I have a 
nested complex structure in one of my EntityTypes which is multivalued.

<Property CollectionKind="List" Name="ValueDetails" Type="myns.ValueDetails"/>

<ComplexType Name="ValueDetails">
     <Property Name="Value" Type="Edm.String"/>
     <Property Name="Timestamp" Type="Edm.DateTime"/>
</ComplexType>

This internal collection of complex type looks like:
<d:ValueDetails>
     <d:element>
         <d:Value>10</d:Value>
         <d:Timestamp>2012-09-07T15:25:04.535+05:30</d:Timestamp>
     </d:element>
</d:ValueDetails>

But when I do getEntities on this EntityType, I get the following Exception:
