Hi all,
I have to add some xml comments for some optional configurations.Since this
configuration is optional Initially this whole xml configuration is
commented. Therefore user have to uncomment this whole configuration to use
it. But I can't insert comments in a another comment. Therefore is it fine
to wrap the comments with a non-existing processing-instructions? [1].
I have attached my configuration file. Please suggest a fine way to make
this configuration file.

Thanks,
Madhawa
