[xml] Distributing xmllint with my app

[Rush Manbert <rush manbert com>]

Are there any restrictions on distribution of xmllint with my 
application? I have built a specialized browser for my extended version 
of xhtml and I would like to give my users the ability to validate their 
source against my DTD. The easy way is to include xmllint (because it's 
built with the same libxml2 version as my app) and run it from within my 
application.

Thanks,
Rush
