The `continuation` attribute

The continuation attribute provides a generic mechanism to establish a logical continuation of the current element cross one or more other elements in the document scope.

The continuation attribute must contain one or more space separated references to the IDs of the associated elements. Note that the element that carries the continuation attribute must not be referenced in this list.

The order in which the references appear in the attribute value is not significant (i.e., the reference order need not match the document order of the referenced elements). Only elements with the same QName as the parent element of the attribute can be referenced (e.g., a paragraph cannot list a table as a continuation). Additionally, only elements following the current element in the document order may be referenced as continuations. Elements that are referenced as continuations must not have continuation attributes themselves.

Logical connections allow for special formatting of elements when generating outputs (to establish the connection between emphasis that continues across multiple paragraphs for braille formatting, for example). When the continuation attribute has been attached to an element, all formatting instructions that apply to that element also apply to all the elements referenced in the attribute. Formatting instructions on the logical siblings, however, do not cascade.

A processing agent that does not recognize logical connections must be able to process each individual element in the continuation without requiring special knowledge of the elements that came before (i.e., inheritance of formatting cannot be assumed).

Usage Example

<p><emph xml:id="em1" class="italic" continuation="em2">
	"Et in Spiritum Sanctum, Dominum et vivificantem, qui ex Patre Filioque procedit. 
	Qui cum Patre et Filio simul adoratur et conglorificatur. Qui locutus est per prophetas.</emph></p>
<p><emph xml:id="em2" class="italic">
	"Et unam Catholicam et Apostolicam Ecclesiam. Confiteor unum Baptisma in remissionem peccatorum. 
	Et exspecto Resurrectionem mortuorum. Et vitam venturi saeculi. Amen."</emph></p>

The `depth` attribute

The depth attribute specifies the nesting depth of the current element in relation to ancestors of the same type.

An element's name alone does not infer an ancestral relationship; the usage context is equally important. For example, the depth of the first index section is not influenced by the number of structural sections that may enclose the index.

The outermost ancestor has the implied depth value 0.

Note: There are 4 different attributes with the name depth. You will find information about the other depth attribute(s) immediately after the presentation of this depth attribute.

Usage Example

<section xml:id="alice-p1" role="part">

The `rend:prefix` attribute

This attribute is contributed by the Source Rendition Feature.

The rend:prefix attribute specifies the symbol used as prefixes to the item children of an unordered list in the source document.

The semantics of the allowed values of this attribute are defined by the CSS list-style-type property.

The value specified in rend:prefix is inherited by any descendant lists, unless such descendant lists specify a rend:prefix attribute themselves. In terms of the CSS cascade, values provided here must be considered as of author origin.

For more specialized symbols than the ones supported by the rend:prefix attribute on list, the rend:prefix attribute on item can be used.

Note: There are 4 different attributes with the name rend:prefix. You will find information about the other rend:prefix attribute(s) immediately before and after the presentation of this rend:prefix attribute.

Usage Example

<list type="unordered" rend:prefix="diamond">
    <item>…</item>
</list>

The `rend:prefix` attribute

This attribute is contributed by the Source Rendition Feature.

The rend:prefix attribute specifies the symbol used as a prefix to the content of the list item element.

The occurrence of this attribute results in the prefix inheritance, as set by the prefix attribute on a list ancestor, ceases to be active, for this item, any following item siblings, and any child lists.

To specify prefix symbols common to multiple list items, see rend:prefix (unordered) and rend:prefix (ordered).

Note: There are 4 different attributes with the name rend:prefix. You will find information about the other rend:prefix attribute(s) immediately before and after the presentation of this rend:prefix attribute.

Usage Example
