Oh, ok. You want a place to put properties. That makes sense. Here is my

2.) Properties of atom:feed go in atom:head

Basically, this means none of the Atom-defined "Common Atom Constructs"
are extensible, although atom:content has a "blob" property.
Off-the-top-of-my-head methods for dealing with existing "Common Atom
1.) Content Construct
You have a "blob". Use it if you have "special" content. A prop
on atom:entry would probably do otherwise.
2.) Person Construct
"But I want to put FOAF in!" No, you want to relate FOAF
information to this entry AND a person. If you have general
person information, it would be bad to boxcar lots of personal info
in an entry. If it relates to the entry, it can be a prop of entry.
If you need to relate extension data to the Person Construct, that
construct provides a handy URI. Refer to it.
3.) Date Construct
Don't extend this. Add a new kind of date.
4.) Identity Constructs
Don't extend this.
5.) Text Constructs (coming soon to a spec near you!)
Don't extend this.
6.) Link Constructs
"But I want an extra attribute!" No, you want to enclose the Link
Construct in an extension element.
There seems to be a tendency around these parts to take a very narrow
view of what a tool that uses syndication formats should be like...
No, there is a very narrow view of the type of information that is
useful in this format, especially in core. General-purpose assertions
are not demonstrably useful in this space, but taking steps to make sure
they work seems reasonable.
