=JSON=
[[JSON Functions#json:parse|json:parse]] and [[JSON Functions#json:serialize|json:serialize]] facilitate a lossless representation of conversion from JSON to XML and back. The transformation is based on the following rules:
# The resulting document has a <code><json/></code> root node.
# Names (keys) of objects are represented as elements:
|<b>[[XQuery Errors#BaseX Errors (BASX)|BASX0015]]</b> is raised if the specified input cannot be parsed as JsonML instance.
