Foyer incompatible with "Foyer XML" files from Siepmann's website

[chr218]

The "Foyer XML" files available within Siepmann's website for the TRAPPE-UA forcefield are incompatible with latest FOYER version 0.7.6.

Code to reproduce behavior

from foyer import Forcefield

trappe = Forcefield(forcefield_files='TraPPE_UA_2_fully_flexible_ethane.xml')

Output:

DocumentInvalid: Element 'ForceField', attribute 'model': The attribute 'model' is not allowed., line 1

I think this error may be due to incorrect syntax on my part.

Hi! Thanks for opening an issue! I have downloaded the XML from the website and see several syntax errors:

• I don't believe our current XML schema allows for a method attribute in the ForceField element. This is why you are getting the above error
• The Bond subelement currently doesn't support a doi attribute. These doi should go in the atom types only.

Has this been fixed? If no, can we get someone from the Siepmann group to address this issue. @ramanishsingh or someone else?
