How do I create an ideal transformer in SimPowerSystems?

The documentation for the Linear Transformer block states that:

 To implement an ideal transformer model, 

 set the winding resistances and inductances

to 0, and the magnetization resistance

and inductance to inf.

I try to create an ideal transformer in the demo model psbtransfo.mdl. However, if I set the parameters accordingly and run the model, I get the following error dialog box:

 Error in block 'Linear Transformer 75kVA 14400-120-120V,

 Parameter 'Rm' must have a finite value

and the following Simulink error:

 Error evaluating 'InitFcn' callback of Voltage Measurement block (mask) 'PQ'. Error using ==> d:/matlab6p5/toolbox/powersys/powersys/private/blocinit (errorInf)

 Parameter error

This bug has been fixed for Release 14 (R14). For previous releases, read below for any possible workarounds:

This is an error in documentation in SimPowerSystems 2.3 (R13).

The documentation should read as follows:

 To implement a quasi-ideal transformer model, 

 set the winding resistances and inductances to 0, 

 and the magnetization inductance Lm to inf. 

 The Rm value must have a finite value. 

 Use a large value such as 1e4.
