Some code to illustrate:
http://pastebin.com/m14dfb5ea
import maya.cmds as cmds
# Create a scene we will save
cmds.file(f=1, new=1)
node = cmds.createNode("transform", name='testNode')
# Add a NON-STORABLE attribute, and set it to a non-default
cmds.addAttr(node, longName='notStorable', storable=False,
defaultValue=0)
cmds.setAttr(node + '.notStorable', 3)
# Save our scene
cmds.file( rename='storableTest_referenced.ma' )
cmds.file( force=True, save=True, type='mayaAscii')
# Now, make a new scene
cmds.file(f=1, new=1)
# Reference in our old scene
cmds.file( 'storableTest_referenced.ma', r=True )
# Check that the non-storable attribute was, in fact, not stored
refNode = cmds.ls("*testNode")[0]
print "Stored Value:", cmds.getAttr(refNode + '.notStorable')
# Set it to a non-default
cmds.setAttr(refNode + '.notStorable', 3)
# Save our referencing scene, reopen it, and check
cmds.file( rename='storableTest_referencing.ma' )
cmds.file( force=True, save=True, type='mayaAscii')
cmds.file( 'storableTest_referencing.ma', o=True )
print "Stored Value:", cmds.getAttr(refNode + '.notStorable')
