VRML Specification error?

It's a minor detail, but the VRML specification at:
http://www.web3d.org/technicalinfo/...1/nodesRef.html

says:
'The fields and events contained within the node declarations are ordered as
follows:

a. eventIns, in alphabetical order;
b. exposedFields, in alphabetical order;
c. fields, in alphabetical order;
d. eventOuts, in alphabetical order. '

However, later in the specification, the Fog node has a different order:
Fog {
exposedField SFColor color 1 1 1 # [0,1]
exposedField SFString fogType "LINEAR"
exposedField SFFloat visibilityRange 0 # [0,)
eventIn SFBool set_bind
eventOut SFBool isBound
}

Shouldn't it be?:
Fog {
eventIn SFBool set_bind
exposedField SFColor color 1 1 1 # [0,1]
exposedField SFString fogType "LINEAR"
exposedField SFFloat visibilityRange 0 # [0,)
eventOut SFBool isBound
}

This just says how they want to list the fields in the document.
In other words they are explaining the style guide they use.
There is no required order of fields. Fields are referenced
by their name.

..... and here they violated their own style guide.
That's all.
