SNMP MIB ERROR scalar's parent node must be simple node Object Not Imported

Question

I have the following file and I get

X-MIB.txt:26: scalar's parent node must be simple node Object Not Imported

X-MIB.txt:35: scalar's parent node must be simple node Object Not Imported

X-MIB.txt:45: scalar's parent node must be simple node Object Not Imported

X-MIB.txt:55: scalar's parent node must be simple node Object Not Imported

Here's the MIB file (after emitting my company name and replacing names with "x" and "y")

Don't import DisplayString from RFC1213-MIB. You are mixing SMIv1 and SMIv2. Import DisplayString from SNMPv2-TC instead.
Try adding an intermediate OBJECT IDENTIFIER between you module identity and xAlert. I was able to get the warning for scalar's parent node must be simple node to go away by doing this.
```
xMibObjects OBJECT IDENTIFIER ::= { x 1 }
xAlert OBJECT IDENTIFIER ::= { xMibObjects 1 }
```

I don't have the text for your Y-MIB, so I couldn't complete the imports.
