Describe the changes that should be applied to the attributes of your model (e.g., set the value of target /sbml:sbml/sbml:model/sbml:listOfParameters/sbml:parameter[@id='k1']/@value to the new value 2.1). For XML-based model languages such as SBML, targets should be XPaths to XML attributes.

The ids and names data will not be exported to SED-ML because these attributes are not supported by SED-ML L1V3. Once simulation tools update to SED-ML L1V4, we will export this information to SED-ML.

The default value of each attribute is provided as a reference. This information will not be encoded into the generated SED-ML document.
