Title: RE: [xml-dev] Namespace problem
Depends if you believe in namespaces or not. Changing name under customer to customerName is not too much different from using a namespace. Except that using a namespace gives (IMHO) better modularization abilities and gives a nice handle for extra semantics (duck and wait for the syntax vs semantics argument to start again).
Think of the URI as part of the element name. {http://mycompany.com/customers}:Name is a "different" element from {http://yourcompany.com/customers}:Name, even if they are to be handled in the same way. It makes sense to put it in a common namespace, not least because it potentially helps resolving version identification.
You do not *have to* agree on the URI - if you each supply a schema for the documents and you use youyr business partner's schema to validate messages from him, then your XML validation will work anyway. Assuming that the elements should have the same meaning, this would not be a good approach.
So yes, agree on a URI, and only change it in future versions of the schema (by mutual consent) if there is a structural change to objects in that namespace.
If agreeing on a URI is a stumbling block, then you have more serious issues to resolve before the partnership succeeds.

Subject: [xml-dev] Namespace problem
Hi All,
Namespaces was introduced to distinguish duplicate attributes and elements.
We associate URI with elements and attributes to distinguish duplicate
elements and attributes.
I have an element <Name> under <Customer> and <product> in the same xml
file.The problem here is that I receive the file from my business partner.We
have decided to use namespace to distinguish duplicate elements and
attributes. The way to distinguish between the 2 <name> tags is with 2
different URI. Does this mean we have to agree upon the URI for Customer and
product tags??
I want to know whether this means that the 2 URI are fixed(they do not
change unless we both agree for a change)?
Please help me. Thanks in advance.
