Illustrates XML is an important development

Question

Illustrates XML is an important development.

Answer 1

This removes two constraints that were holding back Web developments:

1. Dependence upon a single, inflexible document type (HTML) that was being much abused for tasks this was never designed for;

2. The complexity of full SGML, that syntax allows several powerful if hard-to-program options.

It permits the flexible development of user-defined document types. This gives a robust, non-proprietary, verifiable and persistent file format for the transmission and storage of text and data both upon and off the Web; and this removes the more complex options of SGML, making this easier to program for.
