Hi.

Everything's almost fine. Use xsd:any with processContents="lax" or
"strict" and you'll get your generic objects unmarshalled in the
appropriate property. This will be JAXBElement encapsulating the real
value.

Just normally. Either pass it directly to the marshaller or wrap it in
a JAXBElement.

It is hard to say w/o seeing what you actually do.

If you have a lax xsd:any, this may happen in case JAXB could not
parse the contents of the xsd:any. Are you sure you have a declared
global element in your schema that you put into xsd:any as content?
NMElement is probably a concrete implementation of DOM Element from
Xerces.

No, this is typically not necessary.

Some ISO 19115 or similar? :)

Something like ((JAXBElement) vendorExtension.getAny().get(0)).getValue().

I guess you guys just have some problems with schemas. Take a look at
this simple schema fragment:
<xsd:element name="anyCollectionStrict" type="test:AnyCollectionStrict"/>
<xsd:complexType name="AnyCollectionStrict">
<xsd:sequence>
<xsd:any namespace="##any"
processContents="strict" minOccurs="0"
maxOccurs="unbounded"/>
</xsd:sequence>
</xsd:complexType>
<xsd:element name="anyCollectionLax" type="test:AnyCollectionLax"/>
<xsd:complexType name="AnyCollectionLax">
<xsd:sequence>
<xsd:any namespace="##any"
processContents="lax" minOccurs="0"
maxOccurs="unbounded"/>
</xsd:sequence>
</xsd:complexType>
And this XML:
<test:anyCollectionStrict xmlns:test="urn:test">
<test:anyCollectionLax>
<p>test</p>
</test:anyCollectionLax>
</test:anyCollectionStrict>
When you unmarshall this, you'll get JAXBElement with value AnyCollectionStrict.
This value has getAny() - a list consisting of a single JAXBElement
with a value of AnyCollectionLax.
This value has getAny() - a list consisting of a single DOM element
(<p>test</p>).
Bye.
