In case you want to add informative comments to your CAS permission set node in your manifest.xml – for example something like the red line below:
[xml]

.
.

.
.
[/xml]
When you wrap your code into a package and deploy it , here is what you get in the CAS configuration file (stored in ….\12\config\) without any of your IPermission nodes applied:
[xml]

.
. .
.

[/xml]

And here is what ULS log shows :CAS Deployment :
Added CAS Permission Set. Xml :

[xml]



[/xml]
It seems that deployment APIs ignore applying IPermission nodes when there is a comment line in the beginning of PermissionSet. In short,  comments in CAS permission set node is NOT welcome!
