Style conventions

Names or terms that appear in bold style have specific meaning within XSL, XSLT or related technologies, and appear in bold typeface on their first significant occurrence, and thereafter whenever their roles are further defined. Each highlighted occurrence is referenced in the Index.

Text appearing in a mono-spaced font represents example data, usually an XSL or XML fragment. Larger examples are separated from the text:

This is a sample line of text.

Though bold typeface may be used to emphasize part of an example, such as 'look at this word', it does not have the significance described above.

Examples of presented material (printed or displayed output) appear as follows:

This is presented material.

Words displayed in italic style are either quotations or simple 'attention grabbers'.

For the sake of clarity, element and attribute names are capitalized in the text, such as 'the Name element contains a name', but are fully lower case in XML fragment examples, as in '<name>Smith</name>', despite the fact that names are case-sensitive in the XML standard. HTML elements are shown in upper-case (and are not case-sensitive).

Note that mid-Atlantic spelling conventions are used in the text, but some terms and keywords appear with US spelling when consistency with a standard described in this book is important. For example, 'centre' is used in the text but 'center' is a parameter value in the HTML table-formatting model.
