The World-Wide Web Consortium (W3C) has invited users to try out XLink, an XML-based language that will allow several documents to be combined into one on the Internet.
The language enables users to build a document using information from a database, together with graphics and text from other documents that follow the XML specification.
Janet Daly, W3C spokeswoman, said XML documents were like Lego. "Each brick is a separate entity or could be used to build a structure. But you could put a block in any other structure. XLink tells you how to get to a block."
XLink will be used with XML-based language Xpointer, which is used to identify particular blocks of data.
Widely supported by the IT industry, XML is a format that uses tags to describe the structure of a document or an item of information. It is becoming widely used in business applications where data from different systems has to be exchanged.
