Marking Scheme
- 11 mark for correctly expanding XML as 'Extensible Markup Language'.
Hint
Think of the markup language that lets you design your own custom, self-descriptive tags for data exchange.
Quick Oral Answer
XML stands for Extensible Markup Language — a markup language that lets users define their own custom tags to store and exchange structured data.
Analysis & Explanation
XML is one of the standard terms listed under Web Services in the Computer Networks unit, and CBSE regularly asks students to expand such acronyms as one-mark recall questions.
Concept
- XML (Extensible Markup Language) is designed to describe and structure data for storage and exchange between systems.
- Unlike HTML, which has a fixed set of predefined tags for displaying content, XML lets the document author define custom tags suited to the data being represented.
Exam trap
- Students often write 'Extended Markup Language' instead of 'Extensible Markup Language' — the correct word is 'Extensible' (meaning tags can be extended/customised), not 'Extended'.
Common Mistakes
- 1Writing 'Extended Markup Language' instead of the correct 'Extensible Markup Language'.
- 2Confusing XML with HTML, which uses a fixed/predefined set of tags whereas XML allows user-defined tags.
Interesting Facts
XML was released as a W3C Recommendation in February 1998 and was designed to be both human-legible and machine-readable.
Unlike HTML, XML has no predefined tags — the tag names are entirely defined by the document author, which is why XML is widely used in configuration files and data-interchange formats like RSS feeds.
