Here's one: there's no namespace in C
They are(simply put) the things that you import.... EXAMPLE: VB Import (namespace) C# Using (namespace)
An xml schema is written using the syntax and specifications of xml.

No, the use of 'namespace std' is not compulsory. You can specifiy it on any object reference. Specifying 'namespace' simply provides a default value. Contrast ... using namespace std; cout << "Hello world!" << endl; ... with ... std::cout << "Hello world!" << std::endl;
xml can be written straight into html code and vice versa using the correct syntax, ie your html in here and your xml in here
xml is effectively plain text and you can delete passwords using any text editor or even a dedicated xml editor.
XML is actually highly flexible and so has many benefits and advantages, however on the downside it can be quite verbose for certain applications like in web services.
xml uses tags to describe data, any computer can then read the data using the tags.
AIML actually is XML. XML is a meta-language, used to create new languages. AIML is a language created using the XML standard built specifically to aid in the create of AI.
To manipulate an XML document in javascript, you need an XML parser. Today all browsers come with in-built parsers that can parse the XML document. The parser loads the document into your computer's memory. Once the document is loaded, its data can be manipulated using the DOM(Document Object Model). There is significant differences in implementation of Microsoft Browser based XML parser and the Mozilla browsers based XML parser.
The namespace in XML is used to prevent tag naming collisions. Because XML is a meta-language that allows you to define your own elements and attributes, there is significant concern that both you and I might define an element with the same name. For instance, let's imagine that you've created a DTD (Document Type Definition -- the definition file of an XML language) which allows you to define where people sit in a banquet hall. Further, let's pretend I'm hosing a Poker Tournament at your banquet hall. In both DTDs, we have an element called "table." But they mean different things. If we tried to use both DTDs together, a hot mess would ensue. You're data type wouldn't validate against my DTD, and vice versa. So we use namespaces. In XML, we use a namespace by adding the xmlns attribute (that's XML Namespace.) The attribute takes a unique URL as it's value. It's important to note that this value is simply for uniqueness (in other words, it doesn't have to exist. The XML parser will not go looking for it.) I can now attach my namespace directly to my table elements: <table xmlns:p = "http://www.example.com/pokerTable"> ... </table> Further, I define a "prefix" which in this case is p. Now, I can use the prefix when I add a tag. For instance <p:seat>Data</seat> You would use a separate prefix and xlmns value, and this would keep us from stepping on each other's toes.
