Does SVN support some sort of comments in its properties?

I want to use SVN externals on my projects to include a number of third party plugins. I've found this blog post recommending saving the svn:externals value in a file (called svn.externals) with the destination/source pairs, like this:

akismet http://svn.wp-plugins.org/akismet/trunk
all-in-one-seo-pack http://svn.wp-plugins.org/all-in-one-seo-pack/trunk

and to use the the -F flag to set the property, like so:

svn propset svn:externals -F svn.externals

I got the above info from beer planet.

Now to the quesiton. Does SVN support a comment format allowin开发者_如何学编程g me to comment this svn.externals file? I'd like to group the external repositories under libraries, widgets and the like. Also, I was thinking to add instructions on how to update this file/property for my fellow developers at the top of the file. Example, assuming the # starts a comment:

# README: When updating svn:externals
#  1. Update and save this file
#  2. Run 'svn propset svn:externals -F svn.externals
#  3. Commit 'svn ci -m "plugin XXXXXXXX added to svn:externals"'

# wp plugins
wp/content/plugins/akismet http://svn.wp-plugins.org/akismet/trunk
wp/content/plugins/all-in-one-seo-pack http://svn.wp-plugins.org/all-in-one-seo-pack/trunk

# jquery + plugins
js/jquery http://jquery-ui.googlecode.com/svn/trunk
# etc etc (this is just a random example of my idea)

To sum up, my question is, does SVN support some sort of comments in its properties? And if it does, what's the syntax?

From the source code \svn\main.c:1124 (version 1.7.1)

 "      Lines in externals definitions starting with the '#' character\n"
 "      are considered comments and are ignored.\n"

Using # works for comments, as per

I've tested this with 1.6.12, at least.
