Retrieving of the content of stream objects

To follow up, the only thing I found in the PDFSpec was the following:
"
8.4.4 Appearance Streams
Beginning with PDF 1.2, an annotation can specify one or more appearance
streams as an alternative to the simple border and color characteristics available
in earlier versions. Appearance streams enable the annotation to be presented visually
in different ways to reflect its interactions with the user. Each appearance
stream is a form XObject (see Section 4.9, "Form XObjects"): a self-contained
content stream to be rendered inside the annotation rectangle.
"
That last sentance in particular contradicts your observation. I take it that Acrobat has diverged from the spec here?
