A mathematical expression used to define a function in terms of variables and an expression in those variables.
language binding

From Glossary of Document Object Model (DOM) Level 2 HTML Specification (2003-01-09) | Glossary for this source

A programming language binding for an IDL specification is an implementation of the interfaces in the specification for the given language. For example, a Java language binding for the Document Object Model IDL specification would implement the concrete Java classes that provide the functionality exposed by the interfaces.
language identifier

From Voice Extensible Markup Language (VoiceXML) Version 2.0 (2004-03-16) | Glossary for this source

A language identifier labels information content as being of a particular human language variant. Following the XML specification for language identification [XML] , a legal language identifier is identified by an RFC 3066 [RFC3066] code. A language code is required by RFC 3066. A country code or other subtag identifier is optional by RFC 3066.
late normalization

From Requirements for String Identity Matching and String Indexing (1998-07-10) | Glossary for this source

Each individual component that performs a string identity check has to take equivalences into account. This is usually done by normalizing each string to a preferred representation that eliminates duplicates and ambiguities. Because, with late normalization, normalization is done locally and on the fly, there is no need to specify a web-wide uniform normalization.
layout schema (plural: schemata)

From Mathematical Markup Language (MathML) Version 2.0 (2001-02-21) | Glossary for this source

A presentation element defined in chapter 3, other than the token elements and empty elements defined there (i.e. not the elements defined in Section 3.2 [Token Elements] and Section 3.5.5 [Alignment Markers], or the empty elements none and mprescripts defined in Section 3.4.7 [Prescripts and Tensor Indices (mmultiscripts)]). The layout schemata are never empty elements (though their content may contain nothing in some cases), are always expressions, and all allow any MathML expressions as arguments (except for requirements on argument count, and the requirement for a certain empty element in mmultiscripts).
LCS (Laboratory for computer science)

From Glossary of "Weaving the Web" (1999-07-23) | Glossary for this source

LEAD (Live early adoption and demonstration)

From Glossary of "Weaving the Web" (1999-07-23) | Glossary for this source

lexical space

From XForms 1.0 (2003-10-14) | Glossary for this source

From XML Schema [XML Schema part 2]: A lexical space is the set of valid literals for a datatype.

library module

From XQuery 1.0: An XML Query Language (2007-01-23) | Glossary for this source

libwww

line-mode

From Glossary of "Weaving the Web" (1999-07-23) | Glossary for this source

In high and far-off times, people did not see computer programs through windows. They typed commands on a terminal, and the computer replied with text, which was displayed on the screen (or printed on a roll of paper) interleaved with the commands, much as though the person were in a chat session with the computer program. If you have seen a "DOS window," then you have some idea of how people did their communicating with computers in those days, before they learned how to drag and drop. Line-mode is still a very respectable way to communicate with a computer.
A Web client that communicated with the user in line-mode and could run all kinds of computers that did not have windows or mice.
line-mode browser

From Glossary of "Weaving the Web" (1999-07-23) | Glossary for this source

A Web client that communicated with the user in line-mode and could run all kinds of computers that did not have windows or mice.
linearized table

From Web Content Accessibility Guidelines 1.0 (1999-05-05) | Glossary for this source

A table rendering process where the contents of the cells become a series of paragraphs (e.g., down the page) one after another. The paragraphs will occur in the same order as the cells are defined in the document source. Cells should make sense when read in order and should include structural elements (that create paragraphs, headers, lists, etc.) so the page makes sense after linearization.
