SGML - an international standard (ISO 8879-1986) - is a descriptive markup language that describes a documents structure and purpose, rather than its physic
7、al appearance on a page. Due to formatting differences resulting from the use of ULs new electronic publishing system, please note that additional pages (on which no requirements have been changed) may be included in revision pages due to relocation of existing text and reformatting of the Standard.

24、rinted from each single-user version of an electronic Standard. Only one copy of the Standard may be printed for each authorized user of a multiple-user version of an electronic Standard. Because of differences in the computer/software/printer setup used by UL and those of electronic Standards purch
