| The same issue exists in Filter 1.1. And using a function won't help because third party servers won't support the function. I working with Ionic's Redspider server and it can't read our filters. I've made up a work around. I'm adding a hint to the XML Filter Encoding so that you can set the compliance level. When communicating with Geoserver I use the default compliance Ionic is another level (medium) and then there is strict. Ionic allows:
<Filter> <Or> <BBox> some box </BBox> </Or> <FeatureId fid="fid" /> </Filter>
Which is still not legal but is very useful. In the case of NOT( FidFilter ) I'm doing the processing on the client.
We will have to think about how we want to handle this issue in general though.

What you say sounds pretty silly, if needed we can work around it with a function :-( Also note that Filter is available in a BNF form as part of the catalog specification - we really need to take a common ground, and police what is created through the use of specification specific Factories.
I would also ask Justin for comment as he has spent a lot of time on the ground with Filter. Jody Hi,
I've been browsing through the filter spec and to my dismay have learned that the following is not legal:
<Filter> <Or> <BBox> some box </BBox> <FeatureId fid="fid" /> </Or> </Filter>
To be compliant with the spec it is supposed to be:
<Filter> <Or> <BBox> some box </BBox> </Or> <FeatureId fid="fid" /> </Filter>
We also can not do the following:
<Filter> <Not> <FeatureId fid="fid"/> </Not> </Filter>
Our filter implementation allows both so we can't interoperate properly with others because we can make illegal documents....
Looking for comments on what should be done here.
Jesse
