in a model of a 4-brane in the embedding on a 5D space time , ¿have some sense the following embedding?

The brane of coordinates \sigma^u=(t',x',y',z')
the coordinates of space time are : x^M=(t,x,y,z,\phi)

the embedding is : t=konstant, x=x', y=y', z=z', \phi= \phi (t')

which interpretation would have this?
