Elements

data

Data contains the configuration data. Each key must consist of alphanumeric characters, '-', '_' or '.'. Values with non-UTF-8 byte sequences must use the binaryData field. The keys stored in data must not overlap with the keys in the binaryData field, this is enforced during validation process.

binaryData

binaryData contains the binary data, in base64 format. Each key must consist of alphanumeric characters, '-', '_' or '.'. binaryData can contain byte sequences that are not in the UTF-8 range. The keys stored in binaryData must not overlap with the ones in the data field, this is enforced during validation process.
