Metadata dependencies

In some cases the content of the retrieved files depends on, which other metadata types were retrieved.

Profiles

If a package.xml file includes only the type Profiles, it won't download the complete profile files: Sections like pageAccesses, fieldPermissions and tabVisibilities will be missing. In order for these to be included, additional metadata needs to be downloaded.

The following package.xml file will download the most important profile information (based on asagarwal):

Lightning Email Templates

If your Lightning Email Templates include pictures stored in "Setup > Feature Settings > Salesforce Files > Salesforce Files", the respective URLs (in img src) will be replaced with {[devName:asset_name]}. This only works if ContentAsset is included in the package.xml file. Otherwise the img src will be empty.
