 The transformations are defined according to [[#trafo-md]]. The transformation MUST only be of type `translation` or `scale`.
 They MUST contain exactly one `scale` transformation that specifies the pixel size in physical units or time duration. If scaling information is not available or applicable for one of the axes, the value MUST express the scaling factor between the current resolution and the first resolution for the given axis, defaulting to 1.0 if there is no downsampling along the axis.

 Implementations {#implementations}
 ==================================
 
+Partial support {#partial-support}
+----------------------------------
+
+Inevitably, some software libraries and applications will not support this entire specification, but rather some of it. 
+How should partial implementations respond to data defined via unsupported parts of the specification? This specification does not answer this question in general, but it does provide guidance for a specific scenario:
+if a partial implementation normalizes input data, e.g. by converting that data to a form consistent with the subset of the specification supported by the implementation, then 
+the implementation SHOULD provide a clear indication to users and developers when such data normalization occurs. 
+
+For example, suppose an implementation can only represent 3-dimensional images, and additionally that implementation reads 2-dimensional images by converting them internally to a 3-dimensional representation; 
+In this case, the implementation SHOULD make a reasonable effort to inform users that this transformation is occurring, e.g. by displaying an alert message or warning, or by printing relevant information to logs.
+
+This allows implementations flexibility to implement a subset of the specification, while also protecting users from surprising data transformations.
