--------------------------------------
Who is the owner of the service? why there are mix of OData V2 and OData V4
semantics. Not sure changing the prefix value is going to make this right IMO.
> edmx Reference tag Issue

> Key: OLINGO-1079
> URL: https://issues.apache.org/jira/browse/OLINGO-1079
> Project: Olingo
> Issue Type: Bug
> Components: odata2-core
> Reporter: Archana Rai
> Attachments: e488eb6c.diff

>
> Olingo version 2.0 validation as validation failes the edmx due to prefix
> mentioned as below.
> Ex:
> {code}
> <edmx:Edmx xmlns:edmx="http://schemas.microsoft.com/ado/2007/06/edmx";
> xmlns:m="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata";
> xmlns:sap="http://www.sap.com/Protocols/SAPData"; Version="1.0">
> <edmx:Reference xmlns:edmx="http://docs.oasis-open.org/odata/ns/edmx";
> Uri="https://host:port/sap/opu/odata/IWFND/CATALOGSERVICE;v=2/Vocabularies(TechnicalName='%2FIWBEP%2FVOC_COMMON',Version='0001',SAP__Origin='')/$value">
> <edmx:Include Alias="Common" Namespace="com.sap.vocabularies.Common.v1"/>
> </edmx:Reference>
> {code}
> edmx:Reference tags are not supported by the OData V2 specification.
> The root Edmx element is using the OData V2 Edmx namespace with namespace
> prefix edmx:
> <edmx:Edmx xmlns:edmx="http://schemas.microsoft.com/ado/2007/06/edmx";
> The nested Reference element is using the OData V4 Edmx namespace and
> redefines the edmx: prefix
> <edmx:Reference xmlns:edmx="http://docs.oasis-open.org/odata/ns/edmx";
> A better prefix choice would have been edmx4: or anything except edmx:, but
> the XML document is nevertheless correct.
> Section 1.7 of the OData V2 Edmx specification says in
> https://msdn.microsoft.com/en-us/library/dd541467.aspx
> Parsers of EDMX documents ignore content that is unexpected or that cannot be
> parsed.
> So skipping unknown tags should be the default behavior of the Olingo Edmx
> parser.
