Target namespace

[Sam Ruben]

whats the purpose using target namespace in a wsdl?

[Lance Lotlinc]

A target namespace qualifies the children attributes so that you can refer to multiple children that have the same name but different contexts. For example, a child named 'ZipCode' in the 'com.yourcompany.inquiry' namespace might only need a single numeric five digit integer whereas a child named 'ZipCode' in 'gov.usps.www' namespace might need a character string of ten characters in length (zip+four).

Hi Thank you. I just have a doubt. namespace is generally used to avoid conflicts in naming XML tags.

eg:

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
targetNamespace="http://www.w3schools.com"
xmlns="http://www.w3schools.com">

why does the targetNamespace is used here? what the value http://www.w3schools.com is referred to?

xmlns:xs="http://www.w3.org/2001/XMLSchema -- I have understood this point.

targetNamespace is similar as giving package name in java & namespaces in C++. By targetNamespace we specify that the xml is inside the mentioned namespace.
Did that answer or you needed something else?
