If you don't fallow the naming standards and again there isn't any official document or note on naming standards from Microsoft!
Let's get down to details:
1. Create field inside Info path Data Source with naming like
GnG_Name [Capital{Small}Capital_FieldName ]

2. Now Bind those Data fields to form (Table)

3.Publish your form & try to view from browser

Oops! it will break with Unclosed Literal String error (works fine in Client)
4. Reopen the Binding

you will notice field break apart into Gn{Space}G_Name
I think it's kind of small BUG compare to beautiful features offered by Microsoft
Hopefully they will fix the Issue
