[Vala] Question about vala-gen-introspect?

[Peng Huang <shawn p huang gmail com>]

Hello,

I am a newbie of vala. I am writing the vala binding for ibus project. I
want to ask if vala-gen-introspect can support annotations in header files.
Like use (transfer full) to mark the return value of function, to tell
v-g-i, the function will transfer the ownership of the return object to
caller. Are there any documents about it?

Thanks,
Peng Huang
