The <dvrKeyscopePrefix> element specifies the prefix to use when constructing the effective key scope names for the map branch that is implied by the ancestor <ditavalref> element.

For map branches that are implied by <ditavalref> elements, the value of the <dvrKeyscopePrefix> element contributes to the effective key scope names of the branch. The effective key scope names start with the value of the <dvrKeyscopePrefix> element. Note that if the branch as authored does not specify a @keyscope value, specifying <dvrKeyscopePrefix> (without also specifying <dvrKeyscopeSuffix>) results in the branch establishing a key scope whose name is the value of the <dvrKeyscopePrefix> element. The full key scope names also will reflect the value of a <dvrKeyscopeSuffix> element if one is specified, regardless of whether the branch as authored specifies a @keyscope value.

If the <dvrKeyscopePrefix> is specified in the following way:
<topicref keys="branch-01"
  <ditavalref href="condition-01.ditaval">
  <topicref href="topics/subtopic-01.dita"/>

Then the effective key scope name for the branch "branch-01" is "cond01-branch-01".
