Remove "sentinelValues" boolean (not required property)

[dosse]

It should be sufficient to have the optional "Sentinel" value array, which should be called "SentinelValues". Indeed, since it's optional, if there is no value array, it means that there are no sentinel values. An additional boolean seems superfluous.

@dosse does this relate to the XML schemas, the information model, or both? Grateful if you could clarify.

@sdmx3mdt This is related to the schemas.

Also the IM (page 86) is not very clear on this:

Class	Feature	Description
SentinelValuesType		A facet that indicates whether an Attribute or a Measure has sentinel values with special meaning, within their data type.
SentinelValue		A value that has a special meaning within the representation of its Component
	+name	An association of a Sentinel Value to a multilingual name.
	+description	An association of a Sentinel Value to a multilingual description.

'SentinelValuesType" seems not only superfluous but even miss-leading, because it's not about a type. I guess this is why is was renamed in the schemas.

It should really be sufficient to just list sentinel values, if there are any. I don't see a need to add another boolean. The simpler, the better.
