The value of this attribute is always understood to be a single token, even if it contains space or other punctuation characters, and need not be composed of numbers only. It is typically used to specify the numbering of chapters, sections, list items, etc.; it may also be used in the specification of a standard reference system for the text.
<p> … The consequences of this rapid depopulation were the loss of the last <foreign xml:lang="rap">ariki</foreign> or chief (Routledge 1920:205,210) and their connections to ancestral territorial organization.</p>
The xml:lang value will be inherited from the immediately enclosing element, or from its parent, and so on up the document hierarchy. It is generally good practice to specify xml:lang at the highest appropriate level, noticing that a different default may be needed for the teiHeader from that needed for the associated resource element or elements, and that a single TEI document may contain texts in many languages.
The value used must conform with BCP 47. If the value is a private use code (i.e., starts with x- or contains -x-), a language element with a matching value for its ident attribute should be supplied in the TEI header to document this value. Such documentation may also optionally be supplied for non-private-use codes, though these must remain consistent with their (IETF)Internet Engineering Task Force definitions.
<head rend="align(center) case(allcaps)"> <lb/>To The <lb/>Duchesse <lb/>of <lb/>Newcastle, <lb/>On Her <lb/> <hi rend="case(mixed)">New Blazing-World</hi>. </head>
These Guidelines make no binding recommendations for the values of the rend attribute; the characteristics of visual presentation vary too much from text to text and the decision to record or ignore individual characteristics varies too much from project to project. Some potentially useful conventions are noted from time to time at appropriate points in the Guidelines. The values of the rend attribute are a set of sequence-indeterminate individual tokens separated by whitespace.
<head style="text-align: center; font-variant: small-caps"> <lb/>To The <lb/>Duchesse <lb/>of <lb/>Newcastle, <lb/>On Her <lb/> <hi style="font-variant: normal">New Blazing-World</hi>. </head>
Unlike the attribute values of rend, which uses whitespace as a separator, the style attribute may contain whitespace. This attribute is intended for recording inline stylistic information concerning the source, not any particular output.
The formal language in which values for this attribute are expressed may be specified using the styleDefDecl element in the TEI header.
The rendition attribute is used in a very similar way to the class attribute defined for XHTML but with the important distinction that its function is to describe the appearance of the source text, not necessarily to determine how that text should be presented on screen or paper.
Where both rendition and rend are supplied, the latter is understood to override or complement the former.
Each URI provided should indicate a rendition element defining the intended rendition in terms of some appropriate style language, as indicated by the scheme attribute.
