4.13.3 Notes on using HTML parts

If malicious third persons can access Operational Content, they might abuse HTML parts to embed scripts that cause cross-site scripting in the Operational Content. If you use HTML parts in Operational Content, set appropriate access permission for the Operational Content to prevent unauthorized accesses.
If you create large tables or content by using HTML parts, the size of the data to be processed increases, resulting in slower operation of Navigation Platform.
In the same guide area, duplicate name attributes must not be specified for HTML tags. Note, however, that this restriction does not apply to grouping of radio buttons.
When grouping the radio buttons set in an HTML part, always group them in the same HTML part.

For a group of radio buttons in an HTML part, do not specify the name attribute of a radio button in another HTML part placed in the same guide area. Also, do not specify a group name that is the same as that of radio button parts placed elsewhere in the same guide area.
If the data input by the user is to be used by an I/O Plugin, always set a value in the name attribute. In that case, do not specify an empty character string as the value of the name attribute.
When the Suspend/Resume function is used, do not include the <INPUT>, <SELECT>, or <TEXTAREA> tag with the type attribute specified in HTML parts.

These input items are subject to limitations on the storage of suspend information.
