1: False on both counts. Here is an example line
<attribute id="Selectors" type="LSString" value="SelectSkills(ed664663-93b9-4070-a54b-3c7b19c0e7b4,3);SelectSpells(61f79a30-2cac-4a7a-b5fe-50c89d307dd6,2,0,BardCantrip,,,AlwaysPrepared);SelectSpells(dcb45167-86bd-4297-9b9d-c295be51af5b,4,0,BardSpells);SelectEquipment(aab8c5b5-eacf-4867-8e5f-bd4de3a9132e,1,BardInstrument);SelectAbilityBonus(b9149c8e-52c8-46e5-9cb6-fc39301c05fe,AbilityBonus,2,1)"/>
There is a blank before, and sometimes there is something before and/or after it
Otherwise, this is correct.
