Schema validation in case of early available periods

[Lis-TV]

The early available period should not be included into schema check, it generates errors, for example:

At least one BaseURL, SegmentTemplate or SegmentList shall be defined in Period, AdaptationSet or Representation.

Due to ISO/IEC 23009-1:2014(E):

For Early Available Periods, [...]. Such a Period element shall not contain URLs to Media Segments
