When it comes to HTML the UltraPort HL7 Document templates use a slightly modified version of the XHTML standard. If you follow the XHTML rules you can create clean, robust document templates which are only limited by your imagination.
There are really only two (2) major differences between standard XHTML documents and the HTML used to create UltraPort HL7 document templates and they are:
1) You DO NOT include the DOCTYPE entry at the top of your HTML. See below.
2) You DO NOT include any XML namespace entries (xmlns) in your HTML. See below
In the XHTML standard the <!DOCTYPE...> declaration is mandatory, as is the XML namespace in your <html> tag.
XHTML Standard (Bad):
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
