_sections/120-entities.md:This specification uses the `http://www.opendatakit.org/xforms/entities` namespace for attributes added to nodes defined by the ODK XForms spec. In this document, the corresponding prefix used is `entities`.
_sections/120-entities.md:Consumers of the ODK XForms specification may opt into this entities specification but don't have to. For this reason, the entities layer is versioned separately from ODK XForms using the `entities-version` attribute in the `http://www.opendatakit.org/xforms/entities` namespace.
_sections/15-namespaces.md:Elements and attributes that are specific to ODK XForms and not defined by the XForms 1.0 specification should be separately namespaced. For historical reasons, the `"http://openrosa.org/javarosa"` namespace (with the `jr` prefix in this document), and the `"http://openrosa.org/xforms"` namespace (with the `orx` prefix in this document) have been used. For any new additions not defined in another specification, the `"http://www.opendatakit.org/xforms"` namespace is now preferred. It is assigned the `odk` prefix in this documentation. If a new feature is copied from another XForms implementation the originator's namespace will be used.
_sections/20-instance.md:| `odk:prefix` | on the childnode of the primary instance in the _http://opendatakit.org/xforms_ namespace: optional string prefix which is included at the beginning of the [compact representation](#compact-record-representation-(for-sms))
_sections/20-instance.md:| `odk:delimiter` | on the childnode of the primary instance in the _http://opendatakit.org/xforms_ namespace: optional string delimiter which is used to separate prefix, tags and values in the [compact representation](#compact-record-representation-(for-sms))
_sections/20-instance.md:| `odk:tag` | on a question node (grandchild of the primary instance) in the _http://opendatakit.org/xforms_ namespace: optional string tag which is used to identify nodes that should be part of the [compact representation](#compact-record-representation-(for-sms))
