some (other) questions about svn:externals

1) i'm assuming it's not valid to specify an explicit "-rHEAD" as the
revision in an svn:externals reference. (yes, i know that's the
default but, just for fun, i thought i'd try to add it for visual
clarity. boy, did *that* not work out well.)

2) regarding best practice, i note in the latest version of the book
an example of externals:

$ svn propget svn:externals calc
third-party/sounds http://sounds.red-bean.com/repos
third-party/skins ...
third-party/skins/toolkit -r21 ...

obviously, an external reference can represent a subdirectory multiple
levels down, like in that last line. but i could swear i read
somewhere that it's preferable to create the intermediate directories
themselves and that externals should refer only to immediate
subdirectories. am i just imagining this?

3) is there a formally proper way to extract the externals information
from a directory? as part of the build process, i want to grab the
externals revision number info and record that, as in, "this build
incorporated skins -r21, tools -r1.2" and so on.

obviously, i can just use "svn propget" and text cutting to grab that
from within a shell script or makefile. is that the preferred way?
