Confluence User Profile Links in XWiki

1. Confluence User profile Links was migrated in to XWiki.
2. Check screenshots and sample package for reference.
3. Also, i don't know why XWiki is not considering this,
<ac:link><ri:user ri:userkey="ff80808145a6518d0145a72efba90011" /></ac:link>
4. Also i expect the confluence profile to be converted to XWiki user profile link.

Note: Dot(.) & space in username is not accepted in XWiki, hence replace both by underscore( _ ) in XWiki
