If you want to store XML documents intact, the document order matters to 
you, and the entire document must be treated as one logical whole, then a 
native XML storage system may be what you need. For a document of the size 
you mention, here are some important questions:

1. How often is it updated, and at what level of granularity? Updates of 
large single documents are slow on many native-XML systems. Updates of 
smaller documents are generally much faster.
2. Do you need the entire logical structure of the single document? Is 
order significant? If so, you may need to store the entire document as a 
whole. If your system does not support this well for documents of the size 
you anticipate ... you might have a problem.
3. In the stored form, are you going to be normalizing the data to make 
updates more manageable? That has real ramifications for the structure of 
the data....

Also, what CMS system are you using?
