Formatting Output Specification Instance
Formatting Output Specification Instance ( FOSI ) was one of the earliest stylesheet languages . These are generally used to define the specific layout of a digital text separately from the text. So that texts could be displayed according to the stylesheet, the texts had to be structurally marked (" tagged ") in SGML format when using FOSI . So FOSI was a way of defining how B. looks like a heading or a paragraph.
FOSI was developed by the US Department of Defense in the mid-1980s and is considered to be the predecessor of the DSSSL format, which is no longer in use today , which in turn formed the basis of the Extensible Stylesheet Language (XSL) , a standard for describing typesetting instructions for documents that is still accepted today .
FOSI instructions were themselves written in SGML again , an idea that was later taken up again in XSL.
