Question: How are Information Element Names formatted when referred to in a 3GPP specification, such as RANAP signalling documents?
Option 1: All letters in lower case characters, followed by the abbreviation 'IE' in bold font.
Option 2: First letters in each word in upper case characters, with all letters in Italic font, followed by the abbreviation 'IE'.
Option 3: All letters in upper case characters, without any additional formatting, followed by the phrase 'Information Element'.
Option 4: Only the first letter of the first word in upper case, with the rest in lower case, and no special font for the 'IE' abbreviation.
Explanation: This formatting convention is crucial for clear identification of Information Elements within complex signalling specifications like RANAP. The use of upper case characters for the first letter of each word, combined with Italic font for all letters and the 'IE' suffix, provides a visually distinct and standardized way to refer to these elements, facilitating accurate interpretation by implementers and ensuring consistency across the document.
