The next step is to add them for domain checks as well (which is simpler because it doesn't involve validation). This requires the addition of a TrimWhitespaceAdapter for XML JAXB objects, which will prove useful for other @XmlValue attributes in the future. ------------- Created by MOE: https://github.com/google/moe MOE_MIGRATED_REVID=181526726
