xml:any validation - element not allowed(soapUI Pro)

Hi,

We have an issue with xml validation in soapUI Pro:
XSD Definition:

<xs:complexType name="AsyncDotazDataResponseType">
    <xs:annotation>
      <xs:documentation xml:lang="cs">Universal asynchronnous response.</xs:documentation>
    </xs:annotation>
    <xs:sequence>
      <xs:any namespace="##any" minOccurs="0" maxOccurs="unbounded"/>
    </xs:sequence>
  </xs:complexType>

Xml Response:

<odpf:IszrAsyncOdpovedZFrontyDataResponse>
      <odpf:AsyncDotazDataResponse> - this is the AsyncDotazDataResponseType
             <e16:RosPridelIcoResponse>
                ... blahblahblah
             </e16:RosPridelIcoResponse>
      </odpf:AsyncDotazDataResponse>
</odpf:IszrAsyncOdpovedZFrontyDataResponse>

On response validation(alt-V in xml tab) we receive error message:
line xx:Element not allowed(strict wildcard, and no definition found): RosPridelIcoResponse@...somenamespace... in element AsyncDotazDataResponse@...somenamespace...
The RosPridelIcoResponse element IS valid.

Are we doing something wrong, or is there any way to turn off those messages?
Thanks for info
Best Regards
Mark
