What is the full form of "GML"?

GML (Generalized Markup Language) is an IBM document-formatting language that describes a document in terms of its organization structure and content parts and their relationship. GML markup or tag s describe such parts as chapters, important sections and less important sections (by specifying heading levels), paragraphs, lists, tables, and so forth. GML frees document creators from specific document formatting concerns such as font specification, line spacing, and page layout required by IBM's printer formatting language, SCRIPT.
