6. The electronic-document generation system according to claim 1 , wherein said additional information comprises a colour or another symbol.

7. The electronic-document generation system according to claim 1 , further comprising:

a user interface operable to display said target document, or a document generated therefrom, in a first mode in which any such portion having said second status is included in the displayed document, or in a second mode in which any such portion having said second status is excluded from the displayed document.

8. The electronic-document generation system according to claim 7 , wherein said user interface is operable, in said first mode, to include any such additional information in the displayed document and, in said second mode, to exclude any such additional information from the displayed document.

9. A computer-implemented method for generating an electronic target document, the method comprising:

interpreting at least one instruction of a first type and at least one instruction of a second type, each said instruction referring to data and identifying a content item for use in generating said target document, said at least one instruction of a first type and at least one instruction of a second type being respective portions or subroutines of a drafting script that is executed by a processor by evaluating logic expressed within the drafting script in dependence upon data including the referred-to data that is stored in a data source for generating the target document, wherein the referred-to data comprises a value, wherein each of the respective portions or subroutines of the drafting script generates a link that is rendered during execution of the drafting script to allow a user to modify the value via a user interface;

for each instruction of the first type, but not for any instruction of the second type, including the identified content item or content derived therefrom in a corresponding portion of said target document even when a value of the data that the instruction refers to indicates that the content item or the content derived therefrom is to be excluded from the target document;

for each instruction of the second type, but not for any instruction of the first type:

when the value of the data that the instruction refers to indicates that the content item or the content derived therefrom is to be included in the target document, including the identified content item or content derived therefrom in a corresponding portion of said target document; and

when the value of the data that the instruction refers to indicates that the content item or the content derived therefrom is to be excluded from the target document, not including any such content in the target document;

for each said portion corresponding to one of said instructions of the first type:

when the value of the data that the instruction concerned refers to indicates that the content item or the content derived therefrom is to be included in the target document, assigning a first status to that portion, indicating that the content item concerned or the content derived therefrom is to be included in the target document; and

when the value of the data that the instruction concerned refers to indicates that the content item or the content derived therefrom is to be excluded from the target document, assigning a second status to that portion, indicating that the content item concerned or the content derived therefrom is to be excluded from the target document;

for any portion corresponding to one of said instructions of the second type, assigning said first status to that portion;

for each said portion corresponding to one of said instructions of the first type, including additional information in said target document identifying that portion as having said first status or said second status, but, for any portion corresponding to one of said instructions of the second type, not including such additional information in said target document; and

storing the generated target document in a memory of a computer.

10. A non-transitory computer-readable storage medium storing a computer program which, when executed on a computer of an electronic-document generation system, causes the system to:
