leadingSkip property is ignored on enumerations

The leadingSkip property is being ignored when placed on an enumeration type - ex:

<simpleType name="YesNoEnum" dfdlx:repType="my:bit">
<restriction base="xs:string">
<enumeration value="no" dfdlx:repValues="0"/>
<enumeration value="yes" dfdlx:repValues="1"/>
</restriction>
</simpleType>

<element name="yesno" type="YesNoEnum" dfdl:leadingSkip="2"/>

The leading skip is ignored, so we end up looking at the incorrect location in the data.
