Best place to store a big XML.

Where is the best place to store a big XML in the pdf form?

I have a dynamic form which builds some drop down fields using JavaScript and as a source a XML.

While developing, I used a test XML with not that much data and I stored it in a global variable, but when I try to use the production XML, it doesn't fit.

I noticed that a global variable has a length limit of approx 32.000 chars and a text field has 30.000 chars limit, but my XML has more than 100.000 chars.

I also tried to put the XML in a JavaScript variable, but I have to escape some characters and the JavaScript editor fails to show more than 4700 chars on one single line.

So, does anybody know where can I store this big XML?

P.S.: I use LiveCycle Designer ES2 v.9.0.0.2.20101008.2.720808
