AI Summary: Determine whether the presence of a link annotation and/or Ref entry in ISO 14289-2; 8.8 automatically implies 'actionability' or if human semantic interpretation is required to assess whether content 'actionably points' to other content. The task involves analyzing the relevant ISO specifications (ISO 14289-2 and ISO 32000-2) to clarify the ambiguity of the term "actionably points".

AI Summary: The task is to clarify the spline interpolation method used for Type 0 functions in the PDF 2.0 specification. Specifically, the requirements are to explicitly define the boundary conditions (e.g., natural splines) and the type of multi-dimensional spline (e.g., tensor product splines) used for interpolation in the specification's section 7.10.2 and Table 39.

AI Summary: Determine the recommended approach for processors to handle non-standard annotations, specifically addressing whether they should be treated as markup annotations based on functionalities like `Popup` and `RT` grouping. The task involves researching existing PDF specifications (like ISO 32000-2) and potentially contributing to the PDF Association's errata process if a gap is identified.
