Attribute Id (ATTR_ID) changes across environment on migration or re-release

Hi everyone,

We are facing a a peculiar issue with Attribute Ids (ATTR_ID in S_ORDER_ITEM_XA or S_QUOTE_ITEM_XA) changing across environments when we migrate them or make a change a re-release which we did not expect and thought it would remain constant similar to Product Id or Relationship Id

To give you the context, we are integrating with a Self Serve application built on .NET platform and have developed a service which publishes product model. This service in addition to having the product data along with its children has another important field which is Attribute Id which we need to populate and is used to show Attribute Name in the Order Line Item or Quote Line Item Attribute List applet. Since the Attribute Id keeps changing on migration across environment, everytime we give them metadata it is outdated and they have to re-do the whole thing which isnt ideal.
