Own Tags?

[Lee Xu]

Does XML let us to make up our own tags?
Thanks

I am assuming you are talking about custom tags that describe your data. The whole idea behind XML as it indicates in it's name is to be eXtensible meaning you should be able to customize and create your own tags. There are a limited set of predefined tags in XSL namespace which helps you in formatting your xml docs. Hope this helps.

I am a fellow beginner and I posted a similar question somewhere else and no one replied
Isn't XML great? I'm learning as fast as I can.
What's the difference between the Document Type Definition and the Document Type Declaration? Which one is DTD??

[Lee Xu]

Thanks for your reply.
I though DTD is Document Type Definition.

[Stanley Tan]

Yes, me too. So what is a document type declaration and what is the difference?

Hi All,
First of all, The main advantage of XML is introducing Custom Tags in it unlike HTML.
DTD is Document Type Definition. XML DTDs are derived from the SGML. DTDs use a formal grammer to describe the structure and syntax of an XML document. This is used by Validating Parsers.
Here comes the confusing part, DTDs are linked to XML documents using markup called the Document Type Declaration (which is never abbreviated as DTD). This declaration is commonly refered to as "the DOCTYPE declaration" to differentiate it from a DTD.
Thanks.

Thanks for the clarification.
Ok, I've been doing some reading and here's what I've got. The declaration is in the XML file. The DTD doesn't necessarily have to be in the file as the declaration can point to it. This is correct, I hope.
