Experimental!
Google Protocol RPC is an experimental, innovative, and rapidly changing new feature for Google App Engine. Unfortunately, being on the bleeding edge means that we may make backwards-incompatible changes to Google Protocol RPC. We will inform the community when this feature is no longer experimental.
The protobuf wire format uses the Variant class to determine how to transmit a single piece of data. May be used by other formats; see Protocol Buffers Encoding for more information.

Variant has the following values:
BOOL- Boolean value (True or False)
BYTES- String of 8-bit bytes.
DOUBLE- 64-bit floating point number.
ENUM- Enum value (an integer).
FLOAT- 32-bit floating point number.
INT32- 32-bit signed integer.
INT64- 64-bit signed integer.
MESSAGE- Embedded message as byte string.
SINT32- 32-bit signed integer. Uses ZigZag encoding.
SINT64- 64-bit signed integer. Uses ZigZag encoding.
STRING- String of UTF-8-encoded text.
UINT32- 32-bit unsigned integer.
UINT64- 64-bit unsigned integer.
