[DDI-SRG] schema for DDI 3.1

[A. Gregory]

Pascal:

 

It has always been there, in at least one of the schemas.

 

I know this is a weird interpretation of the spec, but when I tested this
most parsers choked if it wasn't declared. Some tools like it, some don't,
but the majority do, from my tests.

 

It is *not* illegal to explicitly declare the xml namespace binding, so long
as it is bound to the namespace stated.

 

Cheers,

 

Arofan

Namespace Constraint: Prefix Declared
The namespace prefix, unless it is xml or xmlns, must have been declared in
a namespace declaration attribute in either the start-tag of the element
where the prefix is used or in an an ancestor element (i.e. an element in
whose content the prefixed markup occurs). The prefix xml is by definition
bound to the namespace name http://www.w3.org/XML/1998/namespace. The prefix
xmlns is used only for namespace bindings and is not itself bound to any
namespace name.

Arofan,
 
I was just checking to see why this came up now but not earlier. It seems 
that
xmlns:xml= <http://www.w3.org/XML/1998/namespace>
"http://www.w3.org/XML/1998/namespace"
 
was not in the first line (<xs:schema  etc) in 3.0. It was simply the 
first import line. Is there a reason for this? Just curious :)

Usually this error is caused by tools which don't like the xml.xsd schema.
 
 
 
Try removing any mention of this from the namespace declarations and
imports, and see if that works.

Hi, all.
 
 
 
I tried to create markup using the draft (?) for 3.1 and my editor would not
load the (Instance) schema.
 
Error:"Namespace prefix is not allowed to start with the reserved string
xml" - line 22, column 639.
 
 
 
Also, could you please let us know when you think 3.1 might actually be
published?
 
Sanda.
