How to find out if you can make an RTF text hyperlink in DOC1 Designer

Product : DOC1 Series 5
Product Feature: Designer
Operating System: Windows 7

Database: SQL2008

DOC1 Version : 5.6.2131 
We have referred the user guide of series 5.6 and it is quite clearly mentioned in the documentation that we do not support URLs in RTF data
• URLs will be converted to plain text. 

So product works as it is designed and there isn't any issue with product.

Refer Page no 317 of the user guide for more details on other restrictions to be considered when generating RTF output.
