Must I using the spring-osgi-namespace in osgi environment?

[ext2]

Hi:
        camel-osgi component give another a spring osgi
namespace."http://camel.apache.org/schema/osgi";.
        But if I use the normal
spring-namespace(http://camel.apache.org/schema/spring), it seems works too
in osgi environment.
        So what's the real different for the osgi namespace?    Must I use
the osgi-namespace in osgi environment?
