<dvrResourcePrefix>The <dvrResourcePrefix> element specifies the prefix to use
when constructing the effective file names of the resources that are referenced from within the
map branch that is implied by the ancestor <ditavalref>
element.
For map branches that are implied by <ditavalref> elements, the
value of the <dvrResourcePrefix> element contributes to the
effective file names of resources that are referenced within the branch. The effective
resource file name starts with the value of the <dvrResourcePrefix>
element. If @copy-to is specified on a topic reference where <dvrResourcePrefix> or <dvrResourceSuffix> based renaming is in effect, the prefixes or suffixes are applied to the resource name inside the @copy-to attribute.
Some resources are not eligible for renaming, such as those marked with
scope="external". Rules for which resources are eligible for renaming,
and what names are allowed as valid resource names, are the same as those for the
@copy-to attribute defined in Topicref element attributes group.
See appendix for information about this element in OASIS document type shells.
+ topic/data ditavalref-d/dvrResourcePrefix
<dvrResourcePrefix> is specified in the following
way:<topicref href="branch-01.dita">
<ditavalref href="condition-01.ditaval">
<ditavalmeta>
<dvrResourcePrefix>cond01-</dvrResourcePrefix>
</ditavalmeta>
</ditavalref>
<topicref href="topics/subtopic-01.dita"/>
</topicref>Then the effective file name of the resource subtopic-01.dita is
cond01-subtopic-01.dita, as though the @copy-to
attribute had been specified with that value on the <topicref>
element that references subtopic-01.dita. Similarly, the effective file name of resource branch-01.dita is
cond01-branch-01.dita.
The following attributes are available on this element: Universal attribute group (except for @conkeyref,
which is removed for all elements in this domain) and the attribute defined below.
