OAXMLWriter (com.viaoa:oa-core 3.7.12 API)

java.lang.Object
- com.viaoa.xml.OAXMLWriter

```
public class OAXMLWriter
extends Object
```
OAXMLWriter creates an XML file that can then be read using an OAXMLReader.
If an object has already been stored in the file, then its key will be stored. NOTE: 20230917 Use OAXml instead (based on OAJson that uses jackson)
