Did Spring abandon YAML to use as an alternative to .properties / .xml because of: [Spring Developer]: ...YAML was considered, but we thought that counting whitespace significant was a support nightmare in the making... [reference from spring forum] I am confident YAML makes a lot of sense for properties, and I am using it currently on the project, but have difficulties to inject properties in a <property name="productName" value="${client.product.name}" /> fashion. Anything I am missing, or I should create a custom YamlPropertyPlaceholderConfigurer ? Thank you, /Anatoly
