A variable tag that outputs the ID of the entry tag in context. The tag context is created by either an MTEntryTags or an MTTags block.
This is not a particularly useful tag but is presented for those who, for example, might want to transfer data between installations or duplicate an installation using template tags.
Like all variable tags, you can apply any of the supported global filters to MTTagID to do further transformations.
