To select the root node of the XML 1.0 specification at http://www.w3.org/TR/REC-xml you can use this URI:
http://www.w3.org/TR/REC-xml#xptr(/)
/ is primarily useful in compound XPointers as a basis
from which to start. In fact, if no absolute location term is included in a
compound location term, / is assumed. However, root()
can also be used to select the entire document in a URI that uses |
to indicate that only a part is normally loaded. For example:
http://www.w3.org/TR/1999/REC-xml|xptr(/)
