about RDF-Schema

Hi,

fist of all there seems to be an error in the "Compact XML Serialization" 
of the "RDF-Schema":

...
<rdf:Property ID="label"
        rdfs:Label="label"
 ...

it should be: rdfs:label="label"
(this error is also in the machine readable description of the RDF schema)


But my main question is about the way the attribute "about" is used in the
RDF-Schema Compact XML Serialization. 

e.g. ... <rdfs:Class about="http://www.w3.org/1999/02/22-rdf-syntax-ns#Statement" ...

For me this would mean: The attribute (in this case "about") will inherit the
namespace of the tag name. So, we would have rdfs:about and not 
rdf:about.  
On the other hand there is:

... <rdfs:Class rdf:ID="Literal" ...

Is there any reason to treat the attributes "ID" and "about" in different ways?

Greetings
Karsten
