This patch adds a clarification note in the Tacker documents
referencing ESTI specification docuemnt indicate that SOL001
v2.6.1 files from external sources may lack required
`occurrences` fields.
The documentation is updated to guide users to use the SOL001
files bundled in Tacker or to manually add the missing fields
to avoid tosca-parser validation errors.
