Pixxi:
They've also stated that if you're unable to provide all of the attributes they now require in the feed, they will work with you to find an acceptable solution.
I think the potential problem is likely to be that Zen doesn't store some of the newly-required Froogle attributes in a standard format (ie field in a table) - for example, 'colour' and 'size' will likely be stored in Zen as Zen attributes, although some shops may use the 'model' field instead.
I believe that will work with you on OPTIONAL attributes and perhaps before on REQUIRED attributes - but I think they have changed their tune now on the REQUIRED ATTRIBUTES

Froogle Merchant Announcement
New product upload requirements
Hello,
As you know, we're always looking for new ways to improve our product search experience, both for our users and for content providers. We've found that one of the most effective ways to help users conduct faster and more effective searches is to describe products with relevant attributes - ideally those assigned by the people who best understand their own products, meaning you.
That's why we're asking all Froogle merchants to send us bulk uploads in the Google Base format, with five additional attributes (along with the basic ones you've submitted in the past). Because we think it's important to provide a consistent user experience, we will no longer list items that don't meet a minimal number of attributes by the end of February 2007. Please review the following bulk uploads - they do not currently meet the minimum attribute requirement:
xxxxxxx
For further explanation please visit our FAQ section
You can review this attribute requirement page to learn about these new guidelines for general product attributes and specific attributes per product type. You can also learn how to submit your feed using Google Base here. We recommend that you include as many attributes as possible; the more information you provide, the better chance you'll have of matching users' "refinement" queries.
We hope you'll continue enjoying the benefits of listing your products on Google, and even increase your potential customer base using the new Google Base format.
Thanks,
The Google Base Team
