Template:Fund sidebar/doc

This template adds a sidebar to pages that are about a fund. The sidebar contains navigation links to other articles relating to the fund.

Usage
Invoke with:

Parameters:
 * Fund: The name of the fund. If a main page exists for the fund, use the page title. Required.
 * HeaderTitle: A short description to appear as the sidebar header title. Required.
 * FundNumber: The Vanguard fund number, used to build the Vanguard website URL. Optional.
 * TrackingError: Tracking error pages are not individual "fund" pages, but rather asset class pages. If one exists, insert the title of the tracking error page. Optional.

Technical notes
The template generates the URL for the Vanguard fund page by passing FundNumber to VanguardFundURL. As a convenience, you can use a fund or ETF ticker as the value for FundNumber, because VanguardFundURL understands these as equivalent.

For example, when passed to VanguardFundURL, FundNumber 0540 generates the following URL:

When using Vanguard fund numbers, do not omit leading zeroes.
