I would like to create something similar to fb: tag.
For example if you put fb:comments in your code it would display your comments from Facebook.
Ofcourse you need to include the Facebook xmlns in your HTML head.
How can I create my own tags to perform for example encryption?
For example: <myEncrypt:key>encrypted word</myEncrypt:key>
Is that possible? I think it is. Can someone give me some directions on how to achive that?
Thanks
Its actually done by javascript (if you are talking about puting fb:… in html). All that you need to do is parse the DOM tree on load of document for particular tag/prefix and process as needed. You can use jQuery or dojo etc for complex queries. Same concept used in dojo for widgets but with custom attribute on tag.
