Using `GL_UNSIGNED_INT_24_8` with `glTexImage2D`

According to the wiki and this answer, it should be possible to use the enums GL_UNSIGNED_INT_24_8 and GL_FLOAT_32_UNSIGNED_INT_24_8_REV with glTexImage2D to upload image data for packed depth stencil formats, but according to the reference pages, these types are not supported by that function (they are listed in the opengl es reference pages).

Is this a mistake in the reference pages, or is it not possible to use these formats for pixel upload? If so, is there a way to upload to this type of texture (other than rendering to it)?

The reference page is missing information (as it is for glTexSubImage2D). And that's not the only missing information. For example, GL_UNSIGNED_INT_5_9_9_9_REV isn't listed as a valid type, but it is listed in the errors section as if it were a valid type. For whatever reason, they've been doing a better job keeping the ES pages updated and accurate than the desktop GL pages.

It's best to look at the OpenGL specification for these kinds of details, especially if you see a contradiction like this.
