2.1.1127 Part 1 Section 19.3.1.36, ph (Placeholder Shape)

a.   The standard states that the placeholder idx attribute specifies the placeholder index.

The following additional restrictions apply to values on the idx attribute:

  • For a placeholder on a Master, Notes Master, Handout Master, Slide Layout or Notes Slide the value shall not be equal to 0xffffffff.

  • For any two placeholders on a Master, Notes Master, Handout Master, Slide Layout or Notes Slide the values must not be the same.

  • For any two placeholders on a Slide with values not equal to 0xffffffff the values shall not be the same.

  • For a placeholder on a Slide with a value not equal to 0xffffffff there shall be a placeholder on the Slide Layout with the same attribute values.

b.   The standard does not specify the inheritance model of a placeholder shape.

PowerPoint defines a placeholder shape on a slide to inherit from the slide layout placeholder with the same idx value, and a placeholder shape on a notes slide to inherit from the notes master placeholder with the same type value.
