/**
 * Information to create a facial expression handle.
 * 
 * Description
 * 
 * Note that although the naming convention for {@code requestedCount} does not align with {@code requestedFacialBlendShapes}, they are coupled together.
 * 
 * The {@link XrFacialExpressionClientCreateInfoML} structure describes the information to create an {@code XrFacialExpressionClientML} handle.
 * 
 * An application specifies the blend shapes they want to query by creating an array of type {@code XrFacialBlendShapeML} and passing it to {@code requestedFacialBlendShapes} along with the corresponding {@code requestedCount}.
 * 
 * The application can also pass in {@code NULL} into {@code requestedFacialBlendShapes} to capture the entirety of {@code XrFacialBlendShapeML}. However, for performance reasons, it may be better to be explicit about what blend shapes to query for performance reasons since some blend shapes may be queried by the runtime at a greater frequency than other blend shapes.
 * 
 * Valid Usage (Implicit)
 * 
 * 
 * The {@link MLFacialExpression XR_ML_facial_expression} extension must be enabled prior to using {@link XrFacialExpressionClientCreateInfoML}
 * {@code type} must be {@link MLFacialExpression#XR_TYPE_FACIAL_EXPRESSION_CLIENT_CREATE_INFO_ML TYPE_FACIAL_EXPRESSION_CLIENT_CREATE_INFO_ML}
 * {@code next} must be {@code NULL} or a valid pointer to the next structure in a structure chain
 * If {@code requestedCount} is not 0, {@code requestedFacialBlendShapes} must be a pointer to an array of {@code requestedCount} valid {@code XrFacialBlendShapeML} values
 * 
 * 
 * See Also
 * 
 * {@link MLFacialExpression#xrCreateFacialExpressionClientML CreateFacialExpressionClientML}, {@link MLFacialExpression#xrDestroyFacialExpressionClientML DestroyFacialExpressionClientML}
 *

 * 
 * 
 * struct XrFacialExpressionClientCreateInfoML {
 *     XrStructureType {@link #type};
 *     void const * {@link #next};
 *     uint32_t {@link #requestedCount};
 *     XrFacialBlendShapeML const * {@link #requestedFacialBlendShapes};
