Changes

All errors are assigned to the {{Code|http://basex.org/errors}} namespace, which is statically bound to the {{Code|bxerr}} prefix.

The standard BaseX JSON format facilitates a lossless conversion from JSON to XML and back. The transformation is based on the following rules:

## If a name has the same type throughout the document, the {{Code|type}} attribute will be omitted. Instead, the name will be listed in additional, type-specific attributes in the root node. The attributes are named by their type in the plural (''numbers'', ''booleans'', ''nulls'', ''objects'' and ''arrays''), and the attribute value contains all names with that type, separated by whitespaces.

The JsonML format can be used to transform XML to JSON and back, using the JsonML dialect. JsonML allows the transformation of arbitrary XML documents, but namespaces, comments and processing instructions will be discarded in the transformation process. More details are found in the official [http://jsonml.org/XML JsonML documentation].
