> 15 Converting to DITA XML > 15.5 Nesting DITA block elements > 15.5.7 Specifying first-child status for nested elements
To specify parent elements in which the paragraph format mapped to a given block element must appear as the first child:
; Frame para format = parents under which the current block element
; (or one of its parents) must be the first child.
If the parent element you assign to a paragraph
format has more than one possible parent, and the paragraph format in
question needs to be first only for one of its possible grandparents,
list both the grandparent and parent, separated by spaces. You can list
as many ancestors as necessary to fully specify first-child status for
the paragraph format. List the ancestors in hierarchical order. The list
must match the ancestor list in [DITAParents]
;
see §15.5.2 Designating DITA ancestor elements.
Use these settings mainly for lists, to ensure
that a paragraph format starts a new list item or a new list. For example,
these settings specify the following for the list paragraph formats mapped
to <p>
in [DITAParaTags]
:
<p>
element must be the first child of
its parent <li>
element, which <li>
element must be the first child of its <ol>
parent; this setting forces first-child status for the entire lineage
of the elements listed, not just the last.
<p>
element or a Bulleted
<p>
element must be the first child of
its parent <li>
element.
If you use definition lists or parameter lists, you must specify first-child status for the paragraph format of the term. For example:
To override the [DITAFirst]
assignment for a given instance of a paragraph, place a DITAFirst
marker in the paragraph. Make the content of the marker
the name(s) of the desired ancestor element(s), in hierarchical order.
A DITAFirst marker specifies that the current block element must
be the first child of its listed ancestor elements, overriding whatever
is specified in [DITAFirst]
.
