Element name capitalization

There seems to be some problem with prefixes. When I look for XML element names that do not strictly follow PascalCase naming convention, but have a fully capitalized prefix (such as XPath; OCSPResponse in AdditionalKeyInfoType, but not X509Digest), I can find two candidate properties in the corresponding JSON definition instead of the expected one. For example: dsb-SignaturePtrType, dsigrw-TransformType (XPath as xpath and xPath), dss2-SignaturePlacementType (XPathAfter as xpathAfter and xPathAfter; XPathFirstChildOf as xpathFirstChildOf and
xPathFirstChildOf), dss2-AdditionalKeyInfoType (OCSPResponse as ocspresponse and ocsp).
