'properties' is a not a built-in way of getting them all, even though it is a subheader in the dictionary (along with elements) for all class listings. It has to be implemented as a specific property of its own. Once upon a time, there were really very few classes that had these, but most of the OS X Cocoa Apple apps do have a 'properties' property for most classes, I've noticed, even when there may be only two or three other properties.
Cocoa Scripting makes it very easy to add a properties property. In most cases it's no code at all -- it's just a couple of lines in the scripting definition:
<property name="properties" code="pALL" type="record" description="All the object’s properties returned as a record." access="r">
<cocoa key="scriptingProperties"/>
</property>
A lot of apps define an item class with a properties property, and have most other classes inherit from that. Of course, if one of the properties returns an error, so will the properties property. Image's file property looks a good candidate for that.
I don't see a properties property defined anywhere in the Pages 5 dictionary, but perhaps there's something else going on there.
