[XSD2Ecore] is removing removing underscore from EEnumLiteral name and not setting literal [message #984678]

I'm running into a name mapping problem where XSD2Ecore is mapping an Restriction with Enumeration Facets to an EENum. Each enumeration value has an underscore, but the corresponding EEnumLiteral's name has the underscore removed and the it's literal is not properly set to original value either. I'll add I don't think removing the underscore should be required to make it a valid Java name anyway.

Is this a bug or am I missing an option somewhere?

Thanks,
dave

Here is the XSD snippet:

    <xsd:simpleType name="DATA-TYPE">
        <xsd:restriction base="xsd:string">
            <xsd:enumeration value="A_INT32"/>
            <xsd:enumeration value="A_UINT32"/>
            <xsd:enumeration value="A_FLOAT32"/>
            <xsd:enumeration value="A_FLOAT64"/>
            <xsd:enumeration value="A_ASCIISTRING"/>
            <xsd:enumeration value="A_UTF8STRING"/>
            <xsd:enumeration value="A_UNICODE2STRING"/>
            <xsd:enumeration value="A_BYTEFIELD"/>
        </xsd:restriction>
    </xsd:simpleType>

And here is generated Ecore (in OCLinEcore):

	enum DATATYPE { serializable }
	{
		annotation _'http:///org/eclipse/emf/ecore/util/ExtendedMetaData'
		(
			name = 'DATA-TYPE'
		);
		literal AINT32;
		literal AUINT32 = 1;
		literal AFLOAT32 = 2;
		literal AFLOAT64 = 3;
		literal AASCIISTRING = 4;
		literal AUTF8STRING = 5;
		literal AUNICODE2STRING = 6;
		literal ABYTEFIELD = 7;
	}

Thanks,
dave

The same problem is happening with dash separated literal names as well. In the dash case the dashes do have to be removed to make them valid Java names, but in that case the literal should have the "unaltered value of the enumeration facet" according to 9.2.2 in the EMF book, correct?

Here is a dash example:

    <xsd:simpleType name="VALID-TYPE">
        <xsd:restriction base="xsd:string">
            <xsd:enumeration value="VALID"/>
            <xsd:enumeration value="NOT-VALID"/>
            <xsd:enumeration value="NOT-DEFINED"/>
            <xsd:enumeration value="NOT-AVAILABLE"/>
        </xsd:restriction>
    </xsd:simpleType>

enum VALIDTYPE {
  VALID = 0;
  NOTVALID = 1;
  NOTDEFINED = 2;
  NOTAVAILABLE = 3;
}

Thanks,
dave

No, the literal is set properly.

Technically the name is valid as long as it doesn't contain
characters that aren't valid Java characters and NCName allows many
such characters. But in general we convert names to use Camel
casee...

That's just how it works. You can use Ecore annotations to specify
exactly the name you want.

It looks like they're not converting the literal value.
