[jdom-interest] how to represent elements that starts with numeric value

[Jeelani]

Hi,

I am working on an application which basically converts an exisiting Contract
from a text document to XML document.

The document contains headings like 

1 Pricing Details
1.1 Tier Pricing

etc..

I would like to know whether there is an easy way of representing the above as XML elements.

thanks,
Jeelani
