WebbBER is a type-length-value encoding, just like Protocol Buffers and Thrift. That means that, as you read bytes that are encoded with BER, first you encounter a type, called in ASN.1 a tag. This is a byte, or series of bytes, that tells you what type of thing is encoded: an INTEGER, or a UTF8String, or a structure, or whatever else.
