Detailed Description

A special value type that can be used to explicitly author an opinion for an attribute's default value or time sample value that represents having no value.

Note that this is different from not having a value authored.

One could author such a value in two ways.

*  attribute->SetDefaultValue(VtValue(SdfValueBlock());
*  ...
*  layer->SetTimeSample(attribute->GetPath(), 101, VtValue(SdfValueBlock()));
*
