Limit with restrictions

Dear list

Is there a possibility to combine the command Limit with parameter
restrictions?

A simple example reads:

p= m^(-1 + a + b + n)*(a/(a + b + n))^a*((b + n)/(a + b + n))^(b +
n)*(a + b + n)

The following restrictions are given:

restrictions = {a > 0, b > 0, n > 0, a + b + n < 1}

Since Limit does not allow restrictions, I tried to combine Limit with
Simplify, since in other examples (e.g. determination of an equation's
sign) this has worked very well:

Simplify[Limit[p, m -> Infinity],restrictions]

Unfortunately, it did not work.

Thanks for your help
