Definition

DEPRECATED: this field is deprecated; use markdown link/text in the _value_ attribute, and "markdown" as the value of the _formatting_ field.

Original usage, prior to RM Release 1.0.4: Optional link sitting behind a section of plain text or coded term item.

12. DvText.formatting
Definition

If set, contains one of the following values:

  • "plain": use for plain text, possibly containing newlines, but otherwise unformatted (same as Void);
  • "plain_no_newlines": use for text containing no newlines or other formatting;
  • "markdown": use for markdown formatted text, strongly recommended in the format of the CommonMark specification.

DEPRECATED usage: contains a string of the form "name:value; name:value..." , e.g. "font-weight : bold; font-family : Arial; font-size : 12pt;". Values taken from W3C CSS2 properties lists for background and font .

16. DvText.language
Definition

Optional indicator of the localised language in which the value is written. Coded from openEHR Code Set languages . Only used when either the text object is in a different language from the enclosing ENTRY, or else the text object is being used outside of an ENTRY or other enclosing structure which indicates the language.

Definition

Name of character encoding scheme in which this value is encoded. Coded from openEHR Code Set character sets . Unicode is the default assumption in openEHR, with UTF-8 being the assumed encoding. This attribute allows for variations from these assumptions.
