STM32F103 in VFQFPN36 with 32.768 kHz RTC crystal?

Is it possible for the 36-pin STM32F microcontroller (STM32F103TxU, VFQFPN36 package) to use an external LSE crystal?  Based on the data sheet, it appears to be missing the PC14 (OSC32_IN) and PC15 (OSC32_OUT) pins.

The support for a 32.768 kHz external RTC crystal is mentioned throughout the data sheet, but is it never mentioned that the VFQFPN36 variant does not support this.  This certainly bears inclusion in the feature matrix somewhere.
