Syntax:

XE field-argument [ switches ]

Description: Defines the text and page number for an index entry, which is used by an INDEX field (§2.16.5.35). The text of the entry is text in field-argument. To indicate a subentry, the main entry text and the subentry text shall be separated by a colon (:). Subentries beyond one level are permitted.

Field Value: None.

Switches: Zero or one of the following field-specific-switches.

\b	Applies bold formatting to the entry's page number. However, if the index style for that entry is already bold, this switch removes that formatting for that entry.
\f field-argument	The text in this switch's field-argument defines an index entry type. If an INDEX field has the same \f switch and field-argument, this entry is included in the resulting index; otherwise, it is excluded.
\i	Applies italic formatting to the entry's page number. However, if the index style for that entry is already italic, this switch removes that formatting for that entry.
\r field-argument	Instead of the entry's page number, uses the range of pages marked by the bookmark specified by text in this switch's field-argument.
\t field-argument	Uses text from field-argument in place of a page number. [Note: Useful for "See …" or "See also …" entries. end note]
\y field-argument	Specifies that the text from field-argument defines the yomi (first phonetic character for sorting indexes) for the index entry.

[Example: Given the following fields spread over a series of pages, and a multi-page bookmark called OOXMLPageRange:

XE "Office Open XML" \b
XE "syntax" \f "Introduction"
XE "behavior:implementation-defined" \b

XE "Office Open XML" \i
XE "behavior:implementation-defined:documenting" \b
XE "grammar" \f "Introduction" \b

XE "Office Open XML"
XE "item: package-relationship" \t "See package-relationship item"

XE "XML" \r OOXMLPageRange
XE "grammar" \f "Introduction"
XE "production" \f "Introduction"

the index produced by INDEX \e "tab" \c "1" \z "1033" is:

implementation-defined ……………………………………. 2

documenting …………………………………….….…….. 3

item

package-relationship ………... See package-relationship item

Office Open XML ……………………………………… 2, 3, 4

XML …………………………………………………….… 1–4

and that produced by INDEX \f "Introduction" \e "tab" \c "1" \z "1033" is:

grammar ………………………………………………..…. 3, 5

production …………………………….................................... 5

syntax ……………………………………………………..…. 2
