inserts a content, such as a text table, text frame or text
field.
Which contents are accepted is implementation-specific. Some
implementations may only accept contents which were created by the
factory that supplied the same text or the document which contains
the text.
Parameter xRange
specifies the position of insertion.
Parameter xContent
the text content to be inserted.
Parameter bAbsorb
specifies whether the text spanned by xRange will be
replaced. If true then the content of xRange will
be replaced by xContent, otherwise xContent
will be inserted at the end of xRange.
