Core utilities for working with various OPC-UA XML schemas.

This crate defines methods for decoding.

• A subset of the XMLSchema schema in schema::xml_schema.
• XML schema for OPC-UA BSD files in schema::opc_binary_schema
• XML schema for OPC-UA types defined in XSD files in schema::opc_ua_types
• XML schema for NodeSet2 files in schema::ua_node_set

XML parsing is done with the roxmltree crate.

Async OPC-UA XML

Part of async-opcua, a general purpose OPC-UA library in rust.

This implements parsing of some XML schemas needed for code generation and loading of NodeSet2 XML files.

Currently, we have support for:

• XSD files, the subset needed for OPC-UA specs.
• OPC-UA BSD files.
• OPC-UA NodeSet2 files.
