SAPUI5中处理模型时partsand有什么用？path

有人可以解释一下以下代码（invoiceJSONModel 在哪里）吗？

<mvc:View
    controllerName="sap.ui.demo.walkthrough.controller.InvoiceList"
    xmlns="sap.m"
    xmlns:mvc="sap.ui.core.mvc">
    <List
            headerText="{i18n>invoiceListTitle}"
        class="sapUiResponsiveMargin"
        width="auto"
        items="{invoice>/Invoices}">
        <items>
            <ObjectListItem
                title="{invoice>Quantity} x {invoice>ProductName}"
                number="{
                    parts: [{path: 'invoice>ExtendedPrice'}, {path: 'view>/currency'}],
                    type: 'sap.ui.model.type.Currency',
                    formatOptions: {
                        showMeasure: false
                    }
                }"
                numberUnit="{view>/currency}"
                numberState="{= ${invoice>ExtendedPrice} > 50 ? 'Error' : 'Success' }">
                <firstStatus>
                    <ObjectStatus text="{
                        path: 'invoice>Status',
                        formatter: '.formatter.statusText'
                    }"/>
                </firstStatus>
            </ObjectListItem>

        </items>
    </List>
</mvc:View>
