Use of HTML as display segments

Overview

A standards based Mechanism for using HTML as display segments in HL7 V2 messages

...

To ensure interoperability the html text should use the HL7V2 subset of the ASCII character set. Unicode characters should be escaped using the standard html escape characters and the resulting html file then placed in the OBX segment. If a free text (FT) OBX value type is used then any reserved HL7 delimiters will need to be escaped using HL7 escape conventions and this will include cursor return/Line feed sequences. If a Encapsulated data (ED) OBX value type is used then the html file should be Base 64 encoded and placed in the appropriate ED field. After extraction from the Base 64 encoding a ASCII encoded html file should be the result.
