- attribute
An attributte makes available extra information regarding the
element on which it appears. The attributes always appear as a
name-value pair on the initialization pointers. Example of an
attribute is id="identification", which gives the
attribute id the value
identification.
- Document Type Definition
(DTD)
A group of statements that define element names and their attributes
specifying the rules for combinations and sequences. It's the
DTD that defines which elements can or cannot
be inserted in the given context.
- DSSSL
DSSSL stands for Document Style Semantics and
Specification Language. It's an ISO standard
(ISO/IEC 10179:1996). The DSSSL standard is
internationally used as a language for documents stylesheets pages for
SGML.
- element
The elements define the hierarchical structure of a document. The
majority of elements have opening and closing pointers. Within these
pointers, pieces of text or even the whole document being written can
be found. There are empty elements which contains only opening
pointers without any content.
- entity
An entity is a name designated for some part of data so that it
can be referenced by a name. The data could be anything from
from simple characters to chapters to sets
of statements of a DTD.
Entity parameters can be generic, external, internal or
SGML data. An entity is similar to a variable
in a programming language, or a macro.
- external entity
An external entity points to an external document. External entities
are used to include texts on certain locations of a
SGML document. It could be used to include
sample screens, legal notes, and chapters for example.
- generic entities
An entity referenced by a name, which starts with
"&" and ends with semicolon is a generic
entity. Most of the time this type of entity is used in the
document and not on the DTD. There are two types
of entities: external and internal. They can refer to special
characters or to text objects such as repeated sentences, names or
chapters.
- internal entity
An internal entity refers to part of the text and is often used
as a shortcut for frequently repeated text.
- parameter entity
An entity often used in the DTD. The entity's
name starts with a percent sign (%) and ends with a
semicolon.
- float
Objects such as side bars, pictures, tables, and charts are called
floats when they don't have a fixed placement on the text. For
printed text, a chart can appear either at the top or at the
bottom of the page. It can also be placed on the next page if it is
too large.
- processing instruction
A processing instruction is a command passed to the document
formatting tool. It starts with "<?". This document
uses processing instructions for naming files when it
is rendered into
HTML: <?dbhtml
filename="file.html">
- SGML
Standard Generalized Markup
Language.
It is an international standard (ISO8879) that
specifies rules for the creation of electronic documents in markup
systems, regardless the work platform used.
- tag
An SGML element bounded by the marks
"<" and ">". Tags are used
to mark the semantic or logical structure of a document. A sample
is the tag <title> to mark the beginning
of a title.
- XML
eXtensible Markup Language. A subproduct of SGML
created specifically for Internet use.
- XSL
XML Style
Language. XSL is to a XML document what a
DSSSL style is for a SGML
document. The XSL is written in
XML.
