When slicing on a value set binding such as here

`

<element id="Observation.component">
<path value="Observation.component" />
<slicing>
<discriminator>
<type value="value" />
<path value="code" />
</discriminator>

<rules value="open" />
</slicing>
</element>

....

<element id="Observation.component:supplementalTypesComponent.code">
<path value="Observation.component.code" />
<binding>
<strength value="required"/>
<valueSet value="http://hl7.org/fhir/uv/phd/ValueSet/CodeableConcept11073MDC"/>
</binding>
</element>

`

The validator returns an information message stating that it cannot find any slice.
