@lpatiny here's the test result. The values seem to be parsed correctly. As for dynamic-typing, these options have been removed in this commit:
https://github.com/cheminfo/arraybuffer-xml-parser/blob/45a57d61f3038cfa6293706562f7c9fb934d6188/src/__tests__/attributesSpec.test.ts

The documentation was not updated.
