Issue 18679: Styling capabilities of Canvas ambiguous (dd-rtf)
Source: Fraunhofer FOKUS (Mr. Max Bureck, max.bureck(at)fokus.fraunhofer.de)
Nature: Clarification
Severity: Minor
Summary: The description of the Canvas element does not say how attributes inherited from GraphicalElement are handled. Since the Canvas explicitly references a background color and a fill, I assume that the attributes "sharedStyle" and "localStyle" are only taken into account for calculation of an effective style of child elements. Since the canvas defines a background, I guess it should fill the parent UI control, so a clip path wouldn't make much sense. Since transforms can also be applied to the fill of an application, I guess the transforms are just applied to the group of containing children. Please clarify, if this assumptions are correct.
