A xml document type is a combination of elements of different types. In some cases your xml document may need to include elements from different locations i.e, all the elements may not be neccessarily declared in a single schema file. And while defining this there can be irregularities if both the sources may have same kind of names for the elements. For example schema 1 may have element by the name product defined. Another schema that you are trying to import may also have same element "product" defined. Now when you combine together you would have two references for the same element product and can be a problem. So they came up with the concept of namespaces which allows you to identify each element of the same time uniquely. Say schema1 product is referenced by ns0:product and other one is referenced by ns1:product. ns0 and ns1 are name space prefixes which actually point to a target namespace.

Target namespace defines the location to which the elements point to i.e, element reference location say www.abctech.com/xyz/1234. You can have as my target namespaces defined.

xml namespace defines the actual structure of the elements that you use in xml i.e, syntax for defining the xml document itself. This can be only one declaration and it is always the same for any xml document.

nenu naku vachinattu ga simple ga cheptanu bayya...but correcto kado cant verify but this is how i can interpret it.
namespace anedi oka container anuko. aa container lo u will define all your "types".
for example namespace url: http://www.andhrafriends.com/example.dtd undi anuko
example lo u will define some like name:String age:number address: String
then xml lo u can use to construct datasets like this:
<details>
<example:name>srini</example:name>
<example:age>25</example:age>
</details>
<details>

<example:name>sapota</example:name>
<example:age>twenty</example:age>
</details>
srini name unna detail will get validated perfectly. but sapota detail will throw error because age is number however its data is "twenty" which is a string.
so age ane element ki definition namespace lo rastam anamata.
xml is structured data. ee structure ela undali ani namespace lo define chestav.
ala u can add multiple namespaces to an xml document and use the elements defined in those namespaces.
hope u got it..
