Semicolons required?

I don't use semicolons as line terminators in TS. Typson breaks without them. Probably shouldn't. Current typescript compiler handles this file fine.

ExpenseModel.ts

/**
 * Date in a string format. Basically can handle anything moment() can handle.
 */
type DateString = string

/**
 * Data Model for Expense report header inbound payload
 */
interface ExpenseHeader {

    /**
     * RefNo
     */
    tranid : string

    /**
     * FullName
     */
    entityid :string

    /**
     * TBD
     */
    trandate : DateString

    /**
     * SubmitDate
     */
    custbody_submitdate

    /**
     * expense line items
     */
    lines : Array<ExpenseLine>
}


interface ExpenseLine {
    /**
     * ExpenseDate
     */
    expensedate : DateString

    /**
     * Descr
     */
    memo: string

    /**
     * Cost
     */
    foreignamount : number,

    /**
     * Currency
     */
    currency : string,

    /**
     * Total
     */
    amount : number

    /**
     * ChargeTo
     */
    custcol_somefieldTDB: string

    /**
     * Customer
     */
    custcol_somecustomer: string

    /**
     * AttachmentID
     */
    custcol_attachment_id: string

    /**
     * tiBillable
     */
    isBillable : boolean

    /**
     * SegmentCode
     *
     */
    expenseCategory: string
}

$typson schema ExpenseModel.ts

(node) sys is deprecated. Use util instead.
ExpenseModel.ts(4,6): error TS1005: ';' expected.
