Detailed Description

namespace for Simulation Description Format parser

The parsing functions read XML elements contained in either a file or string and translates the XML elements into SDF data structures. This translation finds errors in the provided XML, fills in default values, and performs any necessary version related conversions.

XML elements that are not part of the SDF specification are copied in place. This preserves the given XML structure and data.
