###### 3.1.3.1.22 resourceid

The <resourceid> element provides an identifier for applications that require them in a particular format, when the normal id attribute of the topic cannot be used.

Each resourceid entry should be unique. While DITA only requires IDs to be unique within a single topic or map, applications using the resourceid will generally require IDs to be universally unique or unique within a given collection of topics.
