Because there have been some interesting ideas in this thread, I'll add one 
more (which might not be interesting). ;-)

I share the thought that the file / document might be  "a configuration file of 
some sort" and have a suggestion that might be useful in that case, or if the 
document is a program, and maybe even if it is just a text (not necessarily 
plain) file that you open with a word processor.

The thought: put the part of the document that should not be modified in a read 
only file, then "include" that file in another file that you allow to be edited 
(read / write).

There are various ways to do this, depending on the computer language under 
considereration (for example, #include in C / C++).  

There are equivalent approaches in bash, but I forget them (in bash, it might 
be a little more convoluted, like an external / 3rd file that assembles a new 
file from the read-only and read / write files.

I even have a vague recollection that there is / was an "include a file" 
facility in (Microsoft) Word.  And, if so, because LIbre Office seems to make a 
point of providing a feature complete "clone" (mcow) of Word, I suspect there 
is an include facility there as well.
