Yes attachment content is loaded on demand, when you load a page you
get only a list of attachments names.

I'm not sure this is right.
Attachments are not loaded when the doc is loaded (only the list of
attachment is loaded which is a single query to the DB to get the
names) so you can have as many as you want I believe. It's only when
an attachment is manipulated and thus loaded in memory that it takes
up memory space.
Now I haven't tested it for real so I don't really know.
Can someone with more experience qualify this answer?
Is there a limit to the number of files that can be attached to an
XWiki
page? If a page has 199 attachments, would it cause any problems or
issues?
More than the total number of attached files, it's the size of those
files
that might be an issue. Each time a new document is added a new
version of
the page is stored on the database, that has a copy of all the other
documents currently attached to itself. Meaning that if each of your
attached files is 1MB, your total page size is 200MB and each time
you add
an attached file it becomes a bit heavier. Once it becomes really big
operations on that page start taking a lot of time and consume a lot
of
memory resources. To make it short: it will work if you've got
a big computer on the
backend
but it's not recommended.
A better solution would be to create a new page for each file and
list all
the pages you've created (since XE 1.8 you can use a space homepage
for
this).
This is pretty cumbersome and I wouldn't recommend it.
Thanks
