@Thembelani Mlalazi 

Hi, thanks,
1 how bigger is this stream ? xml message have normal limitation to 32k or 64k related to system config
2 can you separate this files and serve on links ?
3 can you encrypt like base64 html images?

i'm not sure have the answer, but i think this questions can help you to get the right path to solution

@Thembelani Mlalazi, he's specifically looking to get at the element %Source, which is not a field defined by the user in the RecordMap, and is not visible to the Context of the Rule.

@Thembelani Mlalazi - when mentioning a DC member in a post it looks like you're copying and pasting the member name in a way that carries over a hyperlink. That hyperlink markup seems to prevent the DC software from recognizing the user. I recommend using the Preview button as a way of checking that the "mention" syntax is correct.

In any case it may be overkill to mention someone who has already contributed to the thread, since they typically get notified of updates unless they have deliberately unsubscribed.

[@Thembelani Mlalazi] - to add a linked mention of another DC member you need to use this syntax.

I posted the above example as an image so the DC software doesn't transform it.

If unsure, try the Preview button before posting.

As a moderator I have edited your first comment to make the mention work as I think you intended.
