Texture Coordinates

I'm writing an .x file parser for OpenGL, and I've encountered a problem when reading the texture coordinates. Somewhere I recall reading that DirectX and OpenGL set up their texture coordinates differently. I know OpenGL's texture coordinates are set up like this:

0,1-----1,1
 |       |
 |       |
0,0-----1,0

I'm wondering how DirectX's coordinates are set up. I've searched google and gamedev, but I can't find anything. Any help is much appreciated.
